<?php
$AL_array = array (
0 => array ( 23 => 1 ) ,
1 => array ( 24 => 2 ) ,
2 => array ( 25 => 3 ) ,
3 => array ( 35 => 4 ) ,
4 => array ( 23 => 1 ) ,
5 => array ( 31 => 2 ) ,
6 => array ( 32 => 1 )
);

foreach( $AL_array as $al ) {
foreach( $al as $key => $level ) {
printf("key %d => level %d\n", $key, $level);
}
