simple example I dont understand:

[joliett89]

<?php
   
   $months = array("January", "February", "March", "April", "May");
   
   $a = 0;
   
   $b = count($months); 
   
   while($a < $b) {
      echo $months[$a], "<br />";
      ++$a;
   }
?>

Elements in the array are assigned a number 0, 1, 2 etc... I did not think about that. I think I get it now. Thank you.

A simpler way of looking at/doing it (IMO):

$months = array("January", "February", "March", "April", "May");

foreach ($months as $month) {
    print $month . '<br /';
}
