array problem

[julian_m]

let's say that I've an array like this:

$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 ) ,
);

and I want to output

key 23 => level 1
key 24 => level 2
key 25 => level 3
key 35 => level 4
key 23 => level 1
key 31=> level 2
key 32=> level 1


I've tried "list" without luck, and I cant see where could be the
problem....


for ($i = 1; $i <= count($AL_array ); $i++){

list($id, $level) = $AL_array[$i];
echo "key $id => level: $level<br>";
}

above code prints

key => level
key => level
key => level
key => level
key => level
key => level
key => level

(without the array values)

Any hint?

Try please this:
/////////////////////////////////////////////////////////////////////////
while(list($id, $level) = each($AL_array) )
{
list($id1, $level1) = each($level);
echo "key $id1 => level: ".$level1."<br> ";
}
/////////////////////////////////////////////////////////////////////////

<?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);
}
}
?>
