simple example I dont understand:

<?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 /';
}
