How to loop different $ names ?

MichaelHe

Is there a way to do this

$valg1 = $_POST['1'];
$valg2 = $_POST['2'];
$valg3 = $_POST['3'];
$valg4 = $_POST['4'];

an easier way. ?

I have make different $'s for a lot of choices in a form, and it would be easier to make it with a FOR command, but how is it done, putting a different number behind the $name ?

Installer

foreach ($_POST as $key => $value) {
    ${'valg' . $key} = $value;
}

Although sticking with an array would be much better:

$valg = $_POST;

How do you mean "sticking with an array" ?

Installer

I meant that the values are in an array already ($_POST), and, since an array is almost always (always?) easier to use than a group of similarly-named scalar variables, that it would probably serve you better to keep them in an array. So that's what I suggest.

OH.

But any way it worked.
Thanks a lot
