preg_match

[Anon]

if ($icq != "") {
if (!preg_match('/^[0-9]+$/', $icq)) {
echo "icq may only contain numbers";
}
}

what's wrong with this ?
when i use it it doesnt give any output and everything just stops

empty screen.. :/

My guess is there is a problem somewhere else.

Put

error_reporting(E_ALL)

at the top of your stript

Why don't you just use is_numeric()

It's much easier

It's much easier, and also very wrong.

is_numeric() will return true for all strings that represent a number, which include "-1" and "6.323,103". ICQ numbers are only positive integers.
