Matching GET values...

All,
I am trying to pass each GET variable to a function and check if it was
expected.
For example, here is a sample link:

index.php?name=modname&file=filename&func=1

the problem is, instead of returning:
match
match
match

it returns:

match
no match
no match
no match
match
no match
no match
no match
match

I know the problem is something with the =each, because it is evaluating
each item against each other, I just don't know how to fix it.

function bmcheck ($bmc, $g)
{
$bmchk = 0;
while (list ($key, $val) = each ($bmc)) {
if ($val == $g) {
echo "match";
echo "<br>";
} else {
echo "no match";
echo "<br>";
}
}
}

$bmc = array("name","file","func");
foreach ($_GET as $gvalue => $g) {
bmcheck($bmc, $gvalue);
}

Basically, when I'm done, if something like this was passed:
index.php?name=modname&file=filename&func=1&bad=no tsupposedtobehere
then I would see 3 "matches" and 1 "no match" for the "bad" parameter.

I hope this makes some sense =)
Thanks.

What's this $bmchk for ? You do not use at all!
Well ... I do :)

}

$bmchk was initialized to 0 before the while() and will only get set to
1 if at least one of the $bmc keys matches the $g parameter.

#> echo "match";

#> } else {
#> echo "no match";

Now all keys have been checked and $bmchk is either 0 (no matches) or 1
(1 or more matches)

if ($bmchk) echo "match<br>";
else echo "no match<br>";

With bmcheck you are trying to reinvent array_key_exists(), sounds kind
of silly to me :)

function bmcheck($arr,$key)
{
if(array_key_exists($key,$arr))
{
echo "match";
}
else
{
echo "nomatch";
}
}
