Digg  get_html_translation_table
Returns the translation table used by htmlspecialchars and htmlentities
(PHP 4, PHP 5)
Example 2411. Translation Table Example<?phpCode Examples / Notes » get_html_translation_tabletrukin
There have been issues when hispanic websites or other websites dont use the corrent collision in mysql. Some problems result that the accents (éä ... ) result in weird characters when a backup is done and restored later on. Or when database is changed to another one. To fix this try something like this function accents($text){ foreach(get_html_translation_table(HTML_ENTITIES) as $a=>$b){ $text = str_replace($a,$b,$text); } return $text; } and use as accents("Hello ....... WITH ACCENTS") and it will return the escaped string. yes
Searching for a fast replacement of the MS WORD special characters which are not covered by get_html_translation_table() , I think the following function might help someone <?php function clean_up($str){ $str = stripslashes($str); $str = strtr($str, get_html_translation_table(HTML_ENTITIES)); $str = str_replace( array("\x82", "\x84", "\x85", "\x91", "\x92", "\x93", "\x94", "\x95", "\x96", "\x97"), array("‚", "„", "…", "‘", "’", "“", "”", "•", "–", "—"),$str); return $str; } ?> It replaces all types of quotes (single and double), horizontal ellipsis (...), bullet, en dash and em dash. edwardzyang
Quite disappointingly, get_html_translation_table() only gives the characters for ISO-8859-1, making it quite useless for UTF-8 or anything else like that (as a previous commenter noticed).

Not sure what's going on here but I've run into a problem that others might face as well... <?php $translations = array_flip(get_html_translation_table(HTML_ENTITIES,ENT_QUOTES)); ?> returns the single quote ' as being equal to ' while <?php $translatedString = htmlentities($string,ENT_QUOTES); ?> returns it as being equal to ' I've had to do a specific string replacement for the time being... Not sure if it's an issue with the function or the array manipulation. -Pat ryan
In XML, you can't assume that the doctype will include the same character entity definitions as HTML. XML authors may require character references instead. The following two functions use get_html_translation_table() to encode data in numeric references. The second, optional argument can be used to substitute a different translation table. function xmlcharacters($string, $trans='') { $trans=(is_array($trans))? $trans:get_html_translation_table(HTML_ENTITIES, ENT_QUOTES); foreach ($trans as $k=>$v) $trans[$k]= "&#".ord($k).";"; return strtr($string, $trans); } function xml_character_decode($string, $trans='') { $trans=(is_array($trans))? $trans:get_html_translation_table(HTML_ENTITIES, ENT_QUOTES); foreach ($trans as $k=>$v) $trans[$k]= "&#".ord($k).";"; $trans=array_flip($trans); return strtr($string, $trans); } alex minkoff
If you want to display special HTML entities in a web browser, you can use the following code: <? $entities = get_html_translation_table(HTML_ENTITIES); foreach ($entities as $entity) { $new_entities[$entity] = htmlspecialchars($entity); } echo "<pre>"; print_r($new_entities); echo "</pre>"; ?> If you don't, the key name of each element will appear to be the same as the element content itself, making it look mighty stupid. ;) alan
If you want to decode all those { symbols as well.... function unhtmlentities ($string) { $trans_tbl = get_html_translation_table (HTML_ENTITIES); $trans_tbl = array_flip ($trans_tbl); $ret = strtr ($string, $trans_tbl); return preg_replace('/\&\#([0-9]+)\;/me', "chr('\\1')",$ret); } maurizio siliani
If you have troubles (like me) getting data from ISO-8859-1 encoded forms where user copy and paste from word, this routine could be useful. It adds to the standard get_html_translation_table the codes of the characters usually M$ Word replacs into typed text. Otherwise those characters would never be displayed correctly in html output. function get_html_translation_table_CP1252() { $trans = get_html_translation_table(HTML_ENTITIES); $trans[chr(130)] = '‚'; // Single Low-9 Quotation Mark $trans[chr(131)] = 'ƒ'; // Latin Small Letter F With Hook $trans[chr(132)] = '„'; // Double Low-9 Quotation Mark $trans[chr(133)] = '…'; // Horizontal Ellipsis $trans[chr(134)] = '†'; // Dagger $trans[chr(135)] = '‡'; // Double Dagger $trans[chr(136)] = 'ˆ'; // Modifier Letter Circumflex Accent $trans[chr(137)] = '‰'; // Per Mille Sign $trans[chr(138)] = 'Š'; // Latin Capital Letter S With Caron $trans[chr(139)] = '‹'; // Single Left-Pointing Angle Quotation Mark $trans[chr(140)] = 'Œ '; // Latin Capital Ligature OE $trans[chr(145)] = '‘'; // Left Single Quotation Mark $trans[chr(146)] = '’'; // Right Single Quotation Mark $trans[chr(147)] = '“'; // Left Double Quotation Mark $trans[chr(148)] = '”'; // Right Double Quotation Mark $trans[chr(149)] = '•'; // Bullet $trans[chr(150)] = '–'; // En Dash $trans[chr(151)] = '—'; // Em Dash $trans[chr(152)] = '˜'; // Small Tilde $trans[chr(153)] = '™'; // Trade Mark Sign $trans[chr(154)] = 'š'; // Latin Small Letter S With Caron $trans[chr(155)] = '›'; // Single Right-Pointing Angle Quotation Mark $trans[chr(156)] = 'œ'; // Latin Small Ligature OE $trans[chr(159)] = 'Ÿ'; // Latin Capital Letter Y With Diaeresis ksort($trans); return $trans; } iain duh workingsoftware.com.au
I wrote a quick little function for converting something like '·' into '·': $to_convert = '·'; $table = get_html_translation_table(HTML_ENTITIES); $equiv = '&#'.ord(array_search($to_convert,$table)).';'; jérôme jaglale
htmlentities includes htmlspecialchars, so here's how to convert an UTF-8 string : htmlentities($string, ENT_QUOTES, 'UTF-8'); dirk
get_html_translation_table It works only with the first 256 Codepositions. For Higher Positions, for Example ф (a kyrillic Letter) it shows the same. zohar
Another way of converting HTML entities into numeric entities to please XML parsers is using two arrays as conversion tables in a preg_replace function. The conversion table mechanism is based on Ryan's examples above. <?php function xmlEntities($s){ //build first an assoc. array with the entities we want to match $table1 = get_html_translation_table(HTML_ENTITIES, ENT_QUOTES); //now build another assoc. array with the entities we want to replace (numeric entities) foreach ($table1 as $k=>$v){ $table1[$k] = "/$v/"; $c = htmlentities($k,ENT_QUOTES,"UTF-8"); $table2[$c] = "&#".ord($k).";"; } //now perform a replacement using preg_replace //each matched value in array 1 will be replaced with the corresponding value in array 2 $s = preg_replace($table1,$table2,$s); return $s; } ?> chris

Alans version didn't seem to work right. If you're having the same problem consider using this slightly modified version instead: function unhtmlentities ($string) { $trans_tbl = get_html_translation_table (HTML_ENTITIES); $trans_tbl = array_flip ($trans_tbl); $ret = strtr ($string, $trans_tbl); return preg_replace('/&#(\d+);/me', "chr('\\1')",$ret); } chris
A lot of quite common characters (or at least not rare, like oelig, euro or minus) are missing from the table unfortunately. Here are some, if you want to make your translation table more complete and your xml data less error-prone. Not sure why some characters have 2 codes, just use one. Here goes: '''=>''', '−'=>'-', 'ˆ'=>'^', '˜'=>'~', 'Š'=>'Š', '‹'=>'‹', 'Œ'=>'Œ', '‘'=>'‘', '’'=>'’', '“'=>'“', '”'=>'”', '•'=>'•', '–'=>'–', '—'=>'—', '˜'=>'˜', '™'=>'™', 'š'=>'š', '›'=>'›', 'œ'=>'œ', 'Ÿ'=>'Ÿ', 'ÿ'=>'ÿ', 'Œ'=>'Œ', 'œ'=>'œ', 'Š'=>'Š', 'š'=>'š', 'Ÿ'=>'Ÿ', 'ƒ'=>'ƒ', 'ˆ'=>'ˆ', '˜'=>'˜', 'Α'=>'Α', 'Β'=>'Β', 'Γ'=>'Γ', 'Δ'=>'Δ', 'Ε'=>'Ε', 'Ζ'=>'Ζ', 'Η'=>'Η', 'Θ'=>'Θ', 'Ι'=>'Ι', 'Κ'=>'Κ', 'Λ'=>'Λ', 'Μ'=>'Μ', 'Ν'=>'Ν', 'Ξ'=>'Ξ', 'Ο'=>'Ο', 'Π'=>'Π', 'Ρ'=>'Ρ', 'Σ'=>'Σ', 'Τ'=>'Τ', 'Υ'=>'Υ', 'Φ'=>'Φ', 'Χ'=>'Χ', 'Ψ'=>'Ψ', 'Ω'=>'Ω', 'α'=>'α', 'β'=>'β', 'γ'=>'γ', 'δ'=>'δ', 'ε'=>'ε', 'ζ'=>'ζ', 'η'=>'η', 'θ'=>'θ', 'ι'=>'ι', 'κ'=>'κ', 'λ'=>'λ', 'μ'=>'μ', 'ν'=>'ν', 'ξ'=>'ξ', 'ο'=>'ο', 'π'=>'π', 'ρ'=>'ρ', 'ς'=>'ς', 'σ'=>'σ', 'τ'=>'τ', 'υ'=>'υ', 'φ'=>'φ', 'χ'=>'χ', 'ψ'=>'ψ', 'ω'=>'ω', 'ϑ'=>'ϑ', 'ϒ'=>'ϒ', 'ϖ'=>'ϖ', ' '=>' ', ' '=>' ', ' '=>' ', '‌'=>'‌', '‍'=>'‍', '‎'=>'‎', '‏'=>'‏', '–'=>'–', '—'=>'—', '‘'=>'‘', '’'=>'’', '‚'=>'‚', '“'=>'“', '”'=>'”', '„'=>'„', '†'=>'†', '‡'=>'‡', '•'=>'•', '…'=>'…', '‰'=>'‰', '′'=>'′', '″'=>'″', '‹'=>'‹', '›'=>'›', '‾'=>'‾', '⁄'=>'⁄', '€'=>'€' |
