Digg mb_substr
Get part of string
(PHP 4 >= 4.0.6, PHP 5)
mb_substr() returns the portion of str specified by the start and length parameters. mb_substr() performs multi-byte safe substr() operation based on number of characters. Position is counted from the beginning of str. First character's position is 0. Second character position is 1, and so on. If encoding is omitted, internal encoding is assumed. encoding is character encoding. If it is omitted, internal character encoding is used. See also mb_strcut(), mb_internal_encoding().

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. |
