How can i determine the number of characters in a string? I am using substr to cut off the last 4 characters of a string. Which is working great. But I want to replace the 3 charcters with "..." only if there are over 20 charcters . I tried substr_replace but it appears on everything no matter how many characters. I am trying to do this is simple terms:

Use strlen(). For example: $String = 'hi my name is'; if (strlen($String) > 20) { $String = substr($String, 0, 17).'...'; } In PHP4, you can use the substr_replace() function to replace the third line in the example above: $String = 'hi my name is'; if (strlen($String) > 20) { $String = substr_replace($String, '...', 17); } For more information, see http://www.php.net/manual/en/function.strlen.php http://www.php.net/manual/en/function.substr.php http://www.php.net/manual/en/function.substr-replace.php -steve

if the string was: hi my name is it is returned shortened to: hi ... Any help appreciated.
