@NogDogNov 10.2009 — #First thing that comes to mind (untested):
"W" is "any non-word character," so it would count a-ZA-Z0-9 and underscores. If you wanted it more restrictive, you would need a more specific regexp, such as '/[^a-ZA-Z]/' to replace anything that is not a letter.
exclude characters from counting?
Hello, I wanted to ask if you have a string like:
[code]
$my_s=’ASRGREGTGTR—-REGREGRE+++RRRRRR….’;
is there a way to count the length of the string, excluding non-word characters (+,- or .)?
thank you

$count = strlen(preg_replace('/W/', '', $string);
