You can use this simple code to convert win-1251 into Unicode. function rus2uni($str,$isTo = true) { $arr = array('Ñ‘'=>'ё','Ð'=>'Ё'); for($i=192;$i<256;$i++) $arr[chr($i)] = ''.dechex($i-176).';'; $str =preg_replace(array('@([а-Ñ]) @i','@ ([а-Ñ])@i'),array('$1 ',' $1'),$str); return strtr($str,$isTo?$arr:array_flip($arr)); } That is useful for xml_parser (to parse windows-1251 files like utf-8). dutoit
To write an XML element $title containing "exotic" (eg. non ASCII é & à ñ...) 2 solutions I found : Fastest : $xml .= "<title><![CDATA[" . $title ."]]></title>\n" or cleanest : $xml .= "<title>".utf8_encode(htmlspecialchars($title))."</title>\n" After that, your xml can be parsed without errors. dimitrisatccfdotauthdotgr
To make utf8_encode and utf8_decode support other than iso-8859-1 encodings, you can easily define your encoding in the PHP source. In the file PHP_SOURCE/ext/xml/xml.c add the following code, for e.g. greek iso-8859-7: DEFINE TWO NEW FUNCTIONS UP TOP: inline static unsigned short xml_encode_iso_8859_7(unsigned char); inline static char xml_decode_iso_8859_7(unsigned short); AND THEN IMPLEMENT THEM BELOW: /* {{{ xml_encode_iso_8859_7() - Dimitris Daskopoulos 28/8/02 */ /* map iso-8859-7 chars to Unicode chars */ inline static unsigned short xml_encode_iso_8859_7(unsigned char c) { if (c < 0x80) { /* low-ASCII, leave as is */ return (unsigned short)c; } else { /* Greek character in high-ASCII */ /* map to UCS greek range (U+0310..03ff) */ /* assume that c < 0xff */ return (unsigned short)(c + 720); } } /* }}} */ /* {{{ xml_decode_iso_8859_7() - Dimitris Daskopoulos 28/8/02 */ /* map Unicode chars to iso-8859-7 chars */ inline static char xml_decode_iso_8859_7(unsigned short c) { if (c < 0x100) { /* char in latin chart, leave as is */ return (char)c; } else if (c > 0x030f && c < 0x0400) { /* char in greek chart */ /* map back to ISO-8859-7 greek (high-ASCII) */ return (char)(c - 720); } else { /* char not in latin or greek Unicode charts */ /* return question mark character */ return (char)('?'); } } /* }}} */ These two work fine for greek iso-8859-7, but studying http://www.unicode.org/charts you can implement mappings between unicode and other iso-8859-x quite easily. In both functions (utf8_encode and utf8_decode), change the requested encoding to the one you prefer, e.g. encoded = xml_utf8_encode(Z_STRVAL_PP(arg), Z_STRLEN_PP(arg), &len, "ISO-8859-7"); decoded = xml_utf8_decode(Z_STRVAL_PP(arg), Z_STRLEN_PP(arg), &len, "ISO-8859-7"); Make sure you add the new encoding in the structure, by entering a new row with the official name (ISO-8859-7), and the names of the two functions you have just defined: xml_encoding xml_encodings[] = { { "ISO-8859-1", xml_decode_iso_8859_1, xml_encode_iso_8859_1 }, { "US-ASCII", xml_decode_us_ascii, xml_encode_us_ascii }, { "UTF-8", NULL, NULL }, { "ISO-8859-7", xml_decode_iso_8859_7, xml_encode_iso_8859_7 }, { NULL, NULL, NULL } }; Finally, the following is probably not necessary, but I changed the default encoding (found in 2 spots in this file) to whatever encoding you prefer in your pages, e.g.: XML(default_encoding) = "ISO-8859-7"; This solution is a little messy, since the utf8_encode function does not accept an argument for choosing the encoding method to use but hardwires the encoding method in the source code. Maybe PHP developers will provide this option in future releases. Until then, this is a quick and dirty solution that will work for localized PHP pages. Dimitris Daskopoulos lars

This does the same thing as some of the posts below (minus the keys), but I thought I'd share anyway cause it is slightly more elegant. Also, its a good example using references such that this could be used as a callback function. function utf_prepare(&$array) { foreach($array AS $key => &$value) { if (is_array($value)) { $this->utf_prepare($value); } else { $value = utf8_encode($value); } } } roylaw

ISO-10646, a super-set of Unicode, uses UTF-8 (there called "UCS", see http://www.unicode.org/faq/utf_bom.html#1 ) in a relaxed variant that supports a 31-bit space encoded into up to six bytes instead of Unicode's 21 bits in up to four bytes.

Re the previous post about converting GB2312 code to Unicode code which displayed the following function: <? // Program by sadly (www.phpx.com) function gb2unicode($gb) { if(!trim($gb)) return $gb; $filename="gb2312.txt"; $tmp=file($filename); $codetable=array(); while(list($key,$value)=each($tmp)) $codetable[hexdec(substr($value,0,6))]=substr($value,9,4); $utf=""; while($gb) { if (ord(substr($gb,0,1))>127) { $this=substr($gb,0,2); $gb=substr($gb,2,strlen($gb)); $utf.="&#x".$codetable[hexdec(bin2hex($this))-0x8080].";"; } else { $gb=substr($gb,1,strlen($gb)); $utf.=substr($gb,0,1); } } return $utf; } ?> I found that a small change was needed in the code to properly handle latin characters embedded in the middle of gb2312 text, as when the text includes a URL or email address. Just reverse the two lines in the part of the statement above that handles ord vals !>127. Change: $gb=substr($gb,1,strlen($gb)); $utf.=substr($gb,0,1); to: $utf.=substr($gb,0,1); $gb=substr($gb,1,strlen($gb)); In the original function, the first latin chacter was dropped and it was not converting the first non-latin character after the latin text (everything was shifted one character too far to the right). Reversing those two lines makes it work correctly in every example I have tried. Also, the source of the gb2312.txt file needed for this to work has changed. You can find it a couple places: http://tcl.apache.org/sources/tcl/tools/encoding/gb2312.txt ftp://ftp.unicode.org/Public/MAPPINGS/OBSOLETE/EASTASIA/GB/GB2312.TXT steven -at- acko -dot- net
Note that you should only use utf8_encode() on ISO-8859-1 data, and not on data using the Windows-1252 codepage. Microsoft's Windows-1252 codepage contains ISO-8859-1, but it includes several characters in the range 0x80-0x9F whose codepoints in Unicode do not match the byte's value (in Unicode, codepoints U+80 - U+9F are unassigned). utf8_encode() simply assumes the bytes integer value is the codepoint number in Unicode. E.g. in 1252, byte 0x80 is the euro sign, which is U+20AC. The same goes for curly quotes, em dashes, etc. utf8_encode() will convert 0x80 into U+0080 (an unassigned codepoint) rather than U+20AC. To convert 1252 to UTF-8, use iconv, recode or mbstring. artem
Loading variables in flash you can lost a lot of hours if your charset is not iso-88951 and you cant' see your characters in flash you must use iconv instead with your codepage (for example windows-1251 for ukrainian, russian) $fw = fopen("flash_input.txt", "w"); if( $fw ) { $utf = iconv("windows-1251","UTF-8",$variable_value); $out = 'variable_name='.$utf; fputs($fw, $out); fclose($fw); } and no urlecode is needed if you save data in file! 27-sep-2006 09:30
In reply to Cundle: Note: The BOM is completely unnecessary in UTF-8. UTF-8 is interpreted the same way regardless of endianness, e.g. Λ (U+039B, GREEK CAPITAL LETTER LAMDA) is represented as the octets 0xCE, 0x9B, always in that order. Extra note: UTF-16 and UCS-2 are different. The same letter would be encoded as 0x03 0x9B on big-endian (e.g. Motorola) architecture, but 0x9B 0x03 on little-endian (e.g Intel) architecture. But in any case, there's nothing wrong with putting a BOM at the beginning of a UTF-8 encoded file. It is just treated as U+FEFF Zero Width No-Break Space. hillar dot petersen
In addition to my previous post. If your values are already in utf-8 maybe you want to utf8_encode array keys only. This will do it: <?php /** * (Recursively) utf8_encode all array keys. * * @param array $array * @return array with utf8_encoded keys */ function utf8_encode_array_keys($array) { $array_type = array_type($array); if ($array_type == "map") { $result_array = array(); foreach($array as $key => $value) { if (is_array($value)) { // recursion $result_array[utf8_encode($key)] = utf8_encode_array_keys($value); } else { // value is not an array, no recursion $result_array[utf8_encode($key)] = $value; } } return $result_array; } else if ($array_type == "vector") { // do not encode anything, just follow the value if it is an array $result_array = array(); foreach ($array as $key => $value) { if (is_array($value)) { // recursion $result_array[$key] = utf8_encode_array_keys($value); } else { // value is not an array, no recursion $result_array[$key] = $value; } } return $result_array; } return false; // argument is not an array, return false } ?> Also note that both this operation (with keys only) and the operation with both keys and values can be reversed by replacing "encode" by "decode". aktionimskript
if you want to put variables as parameter in a flashfile, i prefer using to convert the string with utf8_encode() [or preg_replace, or iconv] and after this i encode it with urlencode(); <?php $yourstring="yourstring"; $str_utf8=utf8_encode($yourstring); $str_encoded=urlencode($str_utf8); echo "<script language='javascript'>"; echo "parameterForFlash='".$str_encoded."';"; echo "</script>"; ?> now you can use the variable (parameterForFlash) in your javascript (plugindetection), that writes the flash object/embed. sts
if you want to encode/decode arrays, use these recursive functions function utf8_encode_array (&$array, $key) { if(is_array($array)) { array_walk ($array, 'utf8_encode_array'); } else { $array = utf8_encode($array); } } function utf8_decode_array (&$array, $key) { if(is_array($array)) { array_walk ($array, 'utf8_decode_array'); } else { $array = utf8_decode($array); } } and call them with array_walk for e.g. array_walk ($array_unencoded, 'utf8_decode_array'); webmaster
if you try to pass data to a flash movie with the actionscripts functions loadVars or sendAndLoad give this a try, if you have problems with special chars like ä ö .... echo "&data1=".urlencode(utf8_encode("äöü")) ."&data2=".urlencode(utf8_encode("ÄÖÜ")); greets js mark
If you haven't guessed already: If the UTF-8 character has no representation in the ISO-8859-1 codepage, a ? will be returned. You might want to wrap a function around this to make sure you aren't saving a bunch of ???? into your database.

If you encoded data with utf8_encode function and you would like to decode it in javascript use library found here: http://www.webtoolkit.info/. There is encoder too.

If you are looking for a function to replace special characters with the hex-utf-8 value (e.g. für Webservice-Security/WSS4J compliancy) you might use this: $textstart = "Größe"; $utf8 =''; $max = strlen($txt); for ($i = 0; $i < $max; $i++) { if ($txt{i} == "&"){ $neu = "&x26;"; } elseif ((ord($txt{$i}) < 32) or (ord($txt{$i}) > 127)){ $neu = urlencode(utf8_encode($txt{$i})); $neu = preg_replace('#\%(..)\%(..)\%(..)#','&#x\1;&#x\2;&#x\3;',$neu); $neu = preg_replace('#\%(..)\%(..)#','&#x\1;&#x\2;',$neu); $neu = preg_replace('#\%(..)#','&#x\1;',$neu); } else { $neu = $txt{$i}; } $utf8 .= $neu; } // for $i $textnew = $utf8; In this example $textnew will be "Größe" hillar dot petersen
If you are interested in recursively converting ISO-8859-1-encoded arrays into UTF-8, then this is one way to do it. Could use a small refactor though. (I used it to prepare some ISO-8859-1 arrays for json_encode. Note that for this to work your values and for associative arrays also your keys must be ISO-8859-1-encoded.) <?php /** * (Recursively) utf8_encode each value in an array. * * @param array $array * @return array utf8_encoded */ function utf8_encode_array($array) { if (is_array($array)) { $result_array = array(); foreach($array as $key => $value) { if (array_type($array) == "map") { // encode both key and value if (is_array($value)) { // recursion $result_array[utf8_encode($key)] = utf8_encode_array($value); } else { // no recursion if (is_string($value)) { $result_array[utf8_encode($key)] = utf8_encode($value); } else { // do not re-encode non-strings, just copy data $result_array[utf8_encode($key)] = $value; } } } else if (array_type($array) == "vector") { // encode value only if (is_array($value)) { // recursion $result_array[$key] = utf8_encode_array($value); } else { // no recursion if (is_string($value)) { $result_array[$key] = utf8_encode($value); } else { // do not re-encode non-strings, just copy data $result_array[$key] = $value; } } } } return $result_array; } return false; // argument is not an array, return false } /** * Determines array type ("vector" or "map"). Returns false if not an array at all. * (I hope a native function will be introduced in some future release of PHP, because * this check is inefficient and quite costly in worst case scenario.) * * @param array $array The array to analyze * @return string array type ("vector" or "map") or false if not an array */ function array_type($array) { if (is_array($array)) { $next = 0; $return_value = "vector"; // we have a vector until proved otherwise foreach ($array as $key => $value) { if ($key != $next) { $return_value = "map"; // we have a map break; } $next++; } return $return_value; } return false; // not array } ?> sadikkeskin
i wrote a function to convert encoding utf8 to iso-8859-9. This function is very useful if you want to use this for ajax. you can apply same way for other languages. <? function str_encode ($string,$to="iso-8859-9",$from="utf8") { if($to=="iso-8859-9" && $from=="utf8"){ $str_array = array( chr(196).chr(177) => chr(253), chr(196).chr(176) => chr(221), chr(195).chr(182) => chr(246), chr(195).chr(150) => chr(214), chr(195).chr(167) => chr(231), chr(195).chr(135) => chr(199), chr(197).chr(159) => chr(254), chr(197).chr(158) => chr(222), chr(196).chr(159) => chr(240), chr(196).chr(158) => chr(208), chr(195).chr(188) => chr(252), chr(195).chr(156) => chr(220) ); return str_replace(array_keys($str_array), array_values($str_array), $string); } return $string; } ?> janci
I was searching for a function similar to Javascript's unescape(). In most cases it is OK to use url_decode() function but not if you've got UTF characters in the strings. They are converted into %uXXXX entities that url_decode() cannot handle. I googled the net and found a function which actualy converts these entities into HTML entities (&#xxx;) that your browser can show correctly. If you're OK with that, the function can be found here: http://pure-essence.net/stuff/code/utf8RawUrlDecode.phps But it was not OK with me because I needed a string in my charset to make some comparations and other stuff. So I have modified the above function and in conjuction with code2utf() function mentioned in some other note here, I have managed to achieve my goal: <?php /** * Function converts an Javascript escaped string back into a string with specified charset (default is UTF-8). * Modified function from http://pure-essence.net/stuff/code/utf8RawUrlDecode.phps * * @param string $source escaped with Javascript's escape() function * @param string $iconv_to destination character set will be used as second paramether in the iconv function. Default is UTF-8. * @return string */ function unescape($source, $iconv_to = 'UTF-8') { $decodedStr = ''; $pos = 0; $len = strlen ($source); while ($pos < $len) { $charAt = substr ($source, $pos, 1); if ($charAt == '%') { $pos++; $charAt = substr ($source, $pos, 1); if ($charAt == 'u') { // we got a unicode character $pos++; $unicodeHexVal = substr ($source, $pos, 4); $unicode = hexdec ($unicodeHexVal); $decodedStr .= code2utf($unicode); $pos += 4; } else { // we have an escaped ascii character $hexVal = substr ($source, $pos, 2); $decodedStr .= chr (hexdec ($hexVal)); $pos += 2; } } else { $decodedStr .= $charAt; $pos++; } } if ($iconv_to != "UTF-8") { $decodedStr = iconv("UTF-8", $iconv_to, $decodedStr); } return $decodedStr; } /** * Function coverts number of utf char into that character. * Function taken from: http://sk2.php.net/manual/en/function.utf8-encode.php#49336 * * @param int $num * @return utf8char */ function code2utf($num){ if($num<128)return chr($num); if($num<2048)return chr(($num>>6)+192).chr(($num&63)+128); if($num<65536)return chr(($num>>12)+224).chr((($num>>6)&63)+128).chr(($num&63)+128); if($num<2097152)return chr(($num>>18)+240).chr((($num>>12)&63)+128).chr((($num>>6)&63)+128) .chr(($num&63)+128); return ''; } ?> mailing
I recommend using this alternative for every language: $new=mb_convert_encoding($s,"UTF-8","auto"); Don't forget to set all your pages to "utf-8" encoding, otherwise just use HTML entities. jcn50. net raven
I often need to convert multi language text sent to me for use in websites and other apps into UTF8 encoded so I can insert it into source code and databases. I knocked up a small web page with its charset set to UTF8 then set it up so I can paste from the original doc (eg word or excel) and have the page return the UTF8 encoded version. Of course the browser will convert the unicode to UTF8 for you as part of the submit (I use IE5 or better for this) then all you have to do in the PHP is encode the UTF8 so the browser will show it in its raw form. Its a bit bulky but I just convert ALL character to html numbered entities (brute force and ignorance does it again.) I've used this to encode everything from Hebrew to Japanese without problems <? header("Content-Type: text/plain; charset=utf-8"); $code = (get_magic_quotes_gpc())?stripslashes($GLOBALS[code]):$GLOBALS[code]; ?> <html> <head> <title>UTF8 ENCODER PAGE</title> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> <form method=post action="?seed=<?=time()?>"> Original Unicode<br /> <textarea name="code" cols="80" rows="10"><?=$code?></textarea><br /> Encoded UTF8<br /> <textarea name="encd" cols="80" rows="10"><? for ($i = 0; $i < strlen($code); $i++) { echo '&#'.ord(substr($code,$i,1)); } ?></textarea><br /> <input type="submit" value="encode"> </form> </body> </html> 18-apr-2007 05:06
I just read what I wrote, sorry for the typos it was a long day: here's the rewritten code: xml_tpl.php <?php header("Content-Type: text/html;charset=ISO-8859-1"); print "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n"; $names=array('jack','bob','vanessa','catherine','valerie'); ?> <parent> <?php foreach($names as $name) {?> <child name="<?php print $name?>" /> <?php } ?> </parent> <?php function create_xml(){ ob_start(); include "xml_tpl.php"; $trapped_content=ob_get_contents(); ob_end_clean(); $file_path= "./somefile.xml"; $file_handle=fopen($file_path,'w'); fwrite($file_handle,utf8_encode($trapped_content)); } ?> james cundle
I had some difficulty finding a way to easily write UTF-8 files with the byte order mark included. This is the simple solution I have come up with: <?php function writeUTF8File($filename,$content) { $dhandle=fopen($filename,"w"); # Now UTF-8 - Add byte order mark fwrite($dhandle, pack("CCC",0xef,0xbb,0xbf)); fwrite($dhandle,$content); fclose($dhandle); } ?> When you read the file back in using fopen, the BOM will also be there. To remove it, I also wrote the following function: <?php function removeBOM($str=""){ if(substr($str, 0,3) == pack("CCC",0xef,0xbb,0xbf)) { $str=substr($str, 3); } return $str; } ?> aidan kehoe

Here's my function to know if one string is encoded in UTF8. If we encode in UTF8 a string or text file that is already encoded in UTF8, it's expected to find the character 'ƒ' ( ALT+159) in the final string. <?php function isUTF8($string) { $string_utf8 = utf8_encode($string); if( strpos($string_utf8,"ƒ",0) !== false ) // "ƒ" is ALT+159 return true; // the original string was utf8 else return false; // otherwise } ?> regards Miguel Díaz http://iubito.free.fr

Hebrew!! What a language.

Good news is that utf8_encode (like UTF-8) passes '<', '>', '/', '\'', '"', etc., so you are free to utf8_encode complete blocks of html text that includes tags. Bad news is that UTF-8 is stupid enough so that utf8_encode(utf8_encode($str)) != utf8_encode($str) in most of the cases. What you can do is write utf8_ensure like: function utf8_ensure($str) { return seems_utf8($str)? $str: utf8_encode($str); } Comes handy when your view library tries to encode the same text multiple times. 27-aug-2002 07:30
For XML generation, if you want non-ASCII ISO-8859-1 characters within text and attributes, you don't absolutely need UTF-8 encoding: The optional XML declaration can change the default encoding for characters from UTF-8 to ISO-8859-1: <?xml version="1.0" encoding="iso-8859-1" ?> This can save a lot of PHP code if you just want to generate ISO-8859-1 text and attribute values... XML specification requires that all parsers support both the UTF-8 encoding (by default), and the ISO-8859-1 character set. Other character sets may be supported also by specifying them in the encoding attribute of the leading XML declaration (but the target parser must support this character set to allow automatic conversion of the source text into Unicode character entities. bisqwit
For reference, it may be insightful to point out that: utf8_encode($s) is actually identical to: recode_string('latin1..utf8', $s) and: iconv('iso-8859-1', 'utf-8', $s) That is, utf8_encode is a specialized case of character set conversions. If your string to be converted to utf-8 is something other than iso-8859-1 (such as iso-8859-2 (Polish/Croatian)), you should use recode_string() or iconv() instead rather than trying to devise complex str_replace statements. penda ekoka
creating utf-8 xml files: this is something that has wasted a lot of my time, I hope this will spare you the headaches: my method consists of creating an xml template that will look like this (this is probably optional, I'm sure you can use good ol' print or echo statements): xml_tpl.php <?php header("Content-Type: text/html;charset=ISO-8859-1"); print "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n"; $names=array('jack','bob','vanessa','catherine','valerie'); ?> <parent> <?php foreach($names as $name) {?> <child name="<?php print $name?>" /> <?php } ?> </parent> ?> from a function or a method I include the previous template and trap the outputted content in an output buffer. The buffured content is then inserted into a file: <?php function create_xml(){ ob_start(); include "xml_php.php"; $trapped_content=ob_get_contents(); ob_end_clean(); $file_path= "./somefile.xml"; $file_handle=fopen($somefile,'w'); fwrite($file_handle,utf8_encode($trapped_content)); } ?> Some side notes: - note that the utf8_encode function goes inside the fwrite() function. - when troubleshooting, make sure to transfer text file (xml included) and scripts in ascii mode when using ftp. For some unknown reason my ftp client did not have xml set as an ascii transfer candidate and was automatically tranfering them in binary. That little "feature" ended up costing me hours of frustration, as the encoding information would just "vanish" between transfer and I kept scratching my head as to why manually created utf8 files were not behaving as they should. rbotzer
BTW, the 21-bit range is pretty old news. Unicode 3.x uses a 31bit encoding scheme that allows for 2 billion characters. I'll post an enhanced encoder soon. In the meanwhile here's the current encoding scheme: http://www.cl.cam.ac.uk/~mgk25/unicode.html#utf-8 Ronen anonymous
