What will be the output of the following PHP code ?

<?php
$p = 2;
while ((--$p > ++$p) - 2)
{   
    print $p;
}
?>

1. 0000000000........infinite time
2. 2222222.........infinite time
3. -2-2-2-2-2-2-2-2.......infinite time
4. All of above
5. None of these

Correct Option: B

(–$p > ++$p) evaluates to 2 but -2 makes it enters the loop and prints p which is 2.
