[PHP] Re: eregi problem

[M. Sokolewicz]

you'd be better off with something like
if(preg_match('#^[a-z0-9]+$#i', $GP['sifre'])) {
        echo 'contains only alphanumeric chars';
} else {
        echo 'contains characters which are not alphanumeric';
}

I m trying to check $GP[sifre] variable, $GP[sifre] must consist of alpha
numeric chars only. here, how I check the variable:
if((eregi("[^a-zA-Z0-9]",$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 ?
