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?
