I assume you're talkina about:

<select multiple.....>


The way to get all the select's multiple values into PHP is to name the select as if it were an array:

<select multiple name="foo[]"....>

When submitted, $_POST['foo'] or $_GET['foo'] will itself be an array containing all the selected values.
