Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 125,531 loops for a total of 2,510,620 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (0.773) milliseconds per 125,531 loops.
- Total difference 15.45 milliseconds for 2,510,620 loops
The iteration variablity for Code 1 was (6.0535) milliseconds and Code 2 was (4.4434) 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']);
