Result: Discarded
The test labeled "time()" was the faster by 0.0567 seconds, (7.537% faster)
The time() test took 0.6955 seconds.
The microtime(true) test took 0.7522 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 182,778 loops for a total of 3,655,560 runs.
- Line execution difference (0.000016) milliseconds.
- Avg difference (2.835) milliseconds per 182,778 loops.
- Total difference 56.69 milliseconds for 3,655,560 loops
The iteration variablity for Code 1 was (3.9082) milliseconds and Code 2 was (8.2372) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "time()", was:
for ($i = 0; $i < 100; $i++) $GLOBALS['dummy'] = time();
The second test, "microtime(true)", was:
for ($i = 0; $i < 100; $i++) $GLOBALS['dummy'] = microtime(true);
