To be able to use the returned value 0 [zero/FALSE] to indicate that the needle was not found when
the needle is also likely to be found at position 0, prepend a char not likely to be part of the
needle string to the haystack:
<?php
$needle='a';
$haystack='ABC';
$xpos=stripos('*'.$haystack,$needle);
if ($xpos>0) {
$xpos=$xpos-1; //adjust the position with respect to $haystack
echo 'Found at offset ' . $xpos;
}
else
echo 'Not found';
?>
