What will be the output of the following PHP code ?

<?php
$s = 2;
for (1; $s == 1; $s = 2)
    {
    print "In for loop statement executed...";
    }
print "After for loop statement executed...\n";
?>

1. After for loop statement executed...
2. Error
3. In for loop statement executed...
4. Nothing
5. None of these

Correct Option: A

The loop never exits as the condition ++s == s is always satisfied,evaluated from right to left.
