You call the script with something like this:

http://www.example.com/script.php?foo[bar]=xyzzy&foo[baz]=moo

This will result in the following array in $_GET:

array(1) { ["foo"]=> array(2) { ["bar"]=> string(5) "xyzzy" ["baz"]=> string(3) "moo" } }

You can also leave out the key names in order to get regular array indexing.

As an aside, instead of passing the array by GET, it might make more sense to store the array in the $_SESSION and get it out again later.

Do you mean like through a form?

<form method="GET" action="action.php">
    <input type="text" name="name[]">
    <input type="text" name="name[]">
    <input type="submit" value="Submit">
</form>

Notice the name attribute has [] in it.

Then in your php:

<?php
    $names = $_GET['name'];
    foreach($names as $name) {
        echo $name . "<br>";
    }
?>

In your query string (or POST data, it doesn't really matter), you should end up with this:

http://example.com/myscript.php?foo[]=1&foo[]=2&foo[]=3

PHP will parse that into $_GET["foo"], and it will be an array with the members 1, 2, and 3. How you mangle that from a form is up to you. In the past, I've named different checkboxes "check[]", for example.
