Why do these nested while loops not work?
- by aliov
I tried and tried and tried to get this code to work and kept coming up with zilch. So I decided to try it using "for loops" instead and it worked first try. Could somebody tell me why this code is no good?
<?php
$x = $y = 10;
while ($x < 100) {
while ($y < 100) {
$num = $x * $y;
$numstr = strval($num);
if ($numstr == strrev($numstr)) {
$pals[] = $numstr;
}
$y++;
}
$x++;
}
?>
