Arrays in PHP 4

[Anon]

To get the value of "foo" from a form, we write $HTTP_GET_VARS["foo"], right? But what do we write to get the value of "foo[]"?

Thanks,
Kevin.

Treat it exactly the same.

$HTTP_GET_VARS["foo"][0]; // like $foo[0]
$HTTP_GET_VARS["foo"][1]; // like $foo[1]

So, this would work too :

foreach ($HTTP_GET_VARS["foo"] as $key => $value) {

print "$key => $value <br>\n";

}

Or even :

$blah = $HTTP_GET_VARS["foo"]

Now $blah is the array.

Great!

Thank you for your excellent answer. Everything is clear now and I can proceed.
