       It is easy to mistake the return values for "character found at
       position 0" and "character not found".  Here's how to detect
       the difference:

if ($pos === false) { // note: three equal signs
    // not found...
}

// in versions older than 4.0b3:
$pos = strrpos($mystring, "b");
if (is_string($pos) &#38;&#38; !$pos) {
    // not found...
}</PRE
