Foreach can be also used to move around multiple tables.
Here is simple example.
<?php
$table[0][0][0] = 6;
$table[0][0][1] = 17;
$table[0][0][2] = 12;
$table[0][0][3] = 8;
$table[0][1][0] = 9;
$table[0][1][1] = 13;
$table[0][1][2] = 11;
$table[0][1][3] = 5;
$table[0][2][0] = 1;
$table[1][1][0] = 4;
$table[1][2][0] = 2;
$table[2][4][1] = 1;
foreach ($table as $i1 => $n1)
foreach ($n1 as $i2 => $n2)
foreach ($n2 as $i3 => $n3)
printf('$table[%d][%d][%d] = %d;<br>', $i1,$i2,$i3,$n3);?>
It gives the result:
$test[0][0][0] = 6;
$test[0][0][1] = 17;
$test[0][0][2] = 12;
$test[0][0][3] = 8;
$test[0][1][0] = 9;
$test[0][1][1] = 13;
$test[0][1][2] = 11;
$test[0][1][3] = 5;
$test[0][2][0] = 1;
$test[1][1][0] = 4;
$test[1][2][0] = 2;
$test[2][4][1] = 1;
