This shows all integers from 1 to 10 that have the 2 least significant bits set:
<?php
for ($i = 1; $i <= 10; $i++) {
if ($i & 3)
{
echo($i . "\n");
}
}
?>

How can I test if a number only has on bit set? So testing different numbers will return TRUE or FALSE: testing 00010000 would return TRUE. testing 00000011 would return FALSE. TIA Charlie
