note 25715 added to function.strlen

It seems to me that all strings in PHP are ASCII, this is fine for some but for me I need more. I thought I would show off a small function that I made that will tell you the length of a UTF-8 string. This comes in handy if you want to restrict the size of user input to say 30 chars - but don't want to force ascii only input on your users. function utf8_strlen($str) { $count = 0; for($i = 0; $i < strlen($str); $i++) { $value = ord($str[$i]); if($value > 127) { if($value >= 192 && $value <= 223) $i++; elseif($value >= 224 && $value <= 239) $i = $i + 2; elseif($value >= 240 && $value <= 247) $i = $i + 3; else die('Not a UTF-8 compatible string'); } $count++; } return $count; } -- http://www.php.net/manual/en/function.strlen.php http://master.php.net/manage/user-notes.php?action=edit+25715 http://master.php.net/manage/user-notes.php?action=delete+25715 http://master.php.net/manage/user-notes.php?action=reject+25715
