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.

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 ?
