Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 146,257 loops for a total of 2,925,140 runs.

Line execution difference (0.000010) milliseconds.
Avg difference (1.391) milliseconds per 146,257 loops.
Total difference 27.82 milliseconds for 2,925,140 loops

The iteration variablity for Code 1 was (6.5266) milliseconds and Code 2 was (4.3637) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "ord()", was:

$GLOBALS['dummy'] = array(
	0 => ord($GLOBALS['packed']{0}),
	1 => ord($GLOBALS['packed']{1}),
	2 => ord($GLOBALS['packed']{2}),
	3 => ord($GLOBALS['packed']{3}),
);

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

$GLOBALS['dummy'] = unpack('C4', $GLOBALS['packed']);
