Result: Discarded
The test labeled "strftime()" was the faster by 0.0213 seconds, (1.771% faster)
The strftime() test took 1.1793 seconds.
The localtime() test took 1.2005 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 289,312 loops for a total of 5,786,240 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (1.063) milliseconds per 289,312 loops.
- Total difference 21.26 milliseconds for 5,786,240 loops
The iteration variablity for Code 1 was (9.6528) milliseconds and Code 2 was (9.9035) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "strftime()", was:
for ($i = 0; $i < 100; $i++) $GLOBALS['dummy'] = (int) strftime('%d', $GLOBALS['t']);
The second test, "localtime()", was:
for ($i = 0; $i < 100; $i++) { $temp = localtime($GLOBALS['t'], true); $GLOBALS['dummy'] = $temp['tm_mday']; }
