php have a "ne" condition like Perl?

[Anon]

I need people to submit a dollar value in a form... when they submit the form it checks to make sure that all the fields are filled out. ie.

if (!$something) {
$error = "fill something in";
} else {
// process form
}

I tried:

if(is_numeric($price)) {
$error = "whatever";
} else {
// process form
}

As you can see in my example, the reverse to what should be happening is occurring. In perl I could use something to the effect:

if ($price ne "numeric") {
$error = "whatever";
} else {
// process form
}

Just wondering if PHP4 has something like this... or how else to go about it. The price can be any amount with and optional 2 decimal places.

Thanks,

I don't mean to sound rude or anything,
but I think this problem calls for a big DUH! :-)

if this:

if(is_numeric($price)) {
$error = "whatever";
} else {
// process form
}

does exactly the opposite of what you want,
wouldn't this:

if(is_numeric($price)) {
// process form
} else {
$error = "whatever";
}

Do exactly what you want?

Or maybe this:

if(!is_numeric($price)) {
$error = "whatever";
} else {
// process form
}
