Code

The first test, "strpos()/strtolower()", was:

for ($j = 0; $j < 40; $j++)
	$GLOBALS['dummy'] = strpos(strtolower($GLOBALS['dummy_match']), '9abcd') === 5;
for ($j = 0; $j < 40; $j++)
	$GLOBALS['dummy'] = strpos(strtolower($GLOBALS['dummy_fail']), '9abcd') === 5;

The second test, "stripos()", was:

for ($j = 0; $j < 40; $j++)
	$GLOBALS['dummy'] = stripos($GLOBALS['dummy_match'], '9abcd') === 5;
for ($j = 0; $j < 40; $j++)
	$GLOBALS['dummy'] = stripos($GLOBALS['dummy_fail'], '9abcd') === 5;
