$haystack contains "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz"

so why does $pos = strpos($haystack, 's'); return me the position of 'S' instead of 's'?

If I wanted a case insensitive search I would use stripos instead.

I cannot confirm this:
<?php
$h = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
$p1 = strpos($h,  's');
$p2 = stripos($h, 's');

echo "strpos position $p1 gives me " . $h{$p1};
echo "\n";
echo "stripos position $p2 gives me " . $h{$p2};
?>

Outputs:

strpos position 44 gives me s
stripos position 18 gives me S

Can you double check?

Tested: Linux, PHP 4.3.2 / 5.0.0
