Get 0 to 9999 in PHP using FOR EACH and Array?

How would I print all values 0...9999 using an array of $array = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9); ? No clue, please help.

$array = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);

foreach ($array as $i) {
   foreach ($array as $j) {
      foreach ($array as $k) {
         foreach ($array as $l) {
            print $i*1000+$j*100+$k*10+$l."\n";
         }
      }
   }
}

Smells like a homework assignment ;)

This would seem like an homework assignment, so some thinking of your own should apply. Example below is specifically strict to the assignment, it is in no way the best solution for just displaying all number between 0 and 9999.

$array = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);

foreach($array as $value_1)
    foreach($array as $value_2)
        foreach($array as $value_3)
            foreach($array as $value_4)
                echo $value_1.$value_2.$value_3.$value_4.PHP_EOL;

<?php
$array = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);
foreach ($array as $a) {
  foreach ($array as $b) {
    foreach ($array as $c) {
      foreach ($array as $d) {

        if ($a) echo $a;
        if ($a || $b) echo $b;
        if ($a || $b || $c) echo $c;

        echo $d. "<br />\n";
      }
    }
  }
}
