Following code:

<?php
$test_array = array();
$test_array['string_index'] = "data in string index";
$test_array[] = "data in index 0";
$test_array[] = "data in index 1";
$test_array[] = "data in index 2";

foreach($test_array as $key => $val)
{
    if($key != 'string_index')
    {
        echo $val."<br>";
    }
}
?>

gives result:

data in index 1
data in index 2

Question is - where is "data in index 0"??? How to get elements from numeric indices 0-n? Also if I change 'string_index' to something else which doesn't exist, it echoes everything except [0]. Plz, explain me this.

Thnx in advance
