Hello, I wanted to ask if you have a string like:
$my_s='ASRGREGTGTR----REGREGRE+++RRRRRR....';
is there a way to count the length of the string, excluding non-word characters (+,- or .)? thank you

You could remove the chars you don't want with a str_replace [php.net] and then just get the length [php.net] of the string afterward. Off the top of my head I can think of like 3 other ways to do this, but the one above seems simplest.

As eelixduppy said, just replace all the non-characters. $my_s='ASRGREGTGTR----REGREGRE+++RRRRRR....';
$chars = preg_replace("/\W/i","", $my_s); echo $chars ."<br>";
echo strlen($chars); Cheers
