[Resolved] [Resolved] easy strlen problem

[knucklehead]

hello
i have an input field in which users should input only letters. but, of course, some of them do not understand that and they are typing some stuff with spaces so when i do strlen on that field i get wrong number. so what should i do to strlen counts only letters but no spaces?
sorry for lame posts but its very late here and my brain is not functioning any more... thanks in advance!

I'm not too proficient with reg exp's, so it could be possible using them. But here's one way of doing things that would get rid of all the spaces and return the length (untested but should work):

function get_length($theString)
{
     $theString = trim($theString);
     $theString = str_replace(" ","",$theString);
     return strlen($theString);
}

Hope this helps 😉

if you want only characters, you should vaildate the input either by checking for spaces, or force it to validate by formatting the invalid data and informing them of the problem, and the corrected data before continuing
