UTF-8 Wordwrap (May 05, 2007)
If you use UTF-8 in your PHP projects you may want to use [wordwrap](http://www.php.net/wordwrap)(). But that function can’t handle multibyte characters and may mess up your text.
Don’t be annoyed - help is near!
The only PHP UTF-8 wordwrap function I found was the one by tjomi4 at yeap dot lv in the notes of the PHP manual. I took it and improved it a bit:
- completly the same syntax as the original wordwrap function:
string utf8_wordwrap(string $str, integer $width, string $break [, bool $cut]); The
$cutparameter is supported (tjomi4’s function only supports$cut = true).
But be careful : I use regular expression word boundaries (\b) for this feature. I’m not sure if this works everywhere!- The function uses the multibyte extension if installed for counting the string length
- The regular expression inside the while loop is shorter and uses
[preg_match](http://www.php.net/preg_match)()instead of[preg_replace](http://www.php.net/preg_replace)(). That should improve performance and prevent a strange bug (Compilation failed: regular expression too large)
