I m trying to check $GP[sifre] variable, $GP[sifre] must consist of alpha numeric chars only. here, how I check the variable: Try this:

if(eregi("^[a-zA-Z0-9]+$",$GP[sifre])) The above say that between the beginning of the string "^" and the end of the string "$", there are only alpha-numeric characters but at least one. Note, your following code has syntax error. Best Bao

if((eregi("[^a-zA-Z0-9]",$GP[sifre]) echo 'true'; else echo 'false'; It works if variable starts with alphabetic chars only. for example this returns 'ok' $GP[sifre]='blabla234243'; but this does not work: (if variable starts with numeric chars) $GP[sifre]='3243242blabla'; second one returns false, couldnt figure out the problem here. any help ?
