[PHP] eregi problem

[emre]

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 ?

Try this:

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.

I think that the ^ anchor is your problem, it shall be out of the brackets :
if (eregi(^[a-zA-Z0-9]+$, $GP['sifre'])) echo 'true';
else echo 'false';
(the above is tested and works perfect)
P.S. Take a look here

 why does this always return wrong char no matter what value is in vpis_ime
 ... i tried blah, 242234 bla242h .. every single time i get wrong
 char. im using PHP 4.1.2

The only thing that will match that regex is a single alpha character.

Try ^[[:alpha:]]+$ (I added a plus) to match one or more.

Try:

if (!eregi('^[a-z_\-]{0,}$', $_POST['vpis_ime']))
  echo wrong char;

That'll sort it for everything except [ and ], which I can't find any way of
checking for :-( Anyone else have any ideas?

HTH anyway.

Danny.
