Almost. But since this is not horseshoes nor hand grenades...
Here is a trap for A/N characters:
if (eregi(^[a-zA-Z0-9]+$,$GP[sifre])) {
corrections to your code:
Move the carat to the outside of the bracket -- I think the carat inside the
bracket means negation (I think). You want a starting character anchor so
that your code translates to start with any of the following.
Add the plus sign after the brackets -- means one or more of the preceding
characters
Add the $ after the + sign -- means only the preceding character can be at
the end of the line. Without the $ as an end anchor the user would be able
to put non-A/N characters at the end of the line of A/N characters and your
code would not trap it.

Subject: [PHP-DB] eregi problem
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 ?
