Digg  mb_substr
Get part of string
(PHP 4 >= 4.0.6, PHP 5)
Code Examples / Notes » mb_substrxiaogil
Thanks Darien from /freenode #php for the following example (a little bit changed). It just prints the 6th character of $string. You can replace the digits by the same in japanese, chinese or whatever language to make a test, it works perfect. <?php mb_internal_encoding("UTF-8"); $string = "0123456789"; $mystring = mb_substr($string,5,1); echo $mystring; ?> (I couldn't replace 0123456789 by chinese numbers for example here, because it's automatically converted into latin digits on this website, look : 零一二三四 五六七八九) gilv silvan
Passing null as length will not make mb_substr use it's default, instead it will interpret it as 0. <?php mb_substr($str,$start,null,$encoding); //Returns '' (empty string) just like substr() ?> Instead use: <?php mb_substr($str,$start,mb_strlen($str),$encoding); ?> drraf
Note: If borders are out of string - mb_string() returns empty _string_, when function substr() returns _boolean_ false in this case. Keep this in mind when using "===" comparisions. Example code: <?php var_dump( substr( 'abc', 5, 2 ) ); // returns "false" var_dump( mb_substr( 'abc', 5, 2 ) ); // returns "" ?> It's especially confusing when using mbstring with function overloading turned on. |
