Historical ResultsBased on (1) saved test runs, The test labeled "time()" was (on average) the faster by 0.0107 seconds, (1.045% faster)
The time() test took 1.0115 seconds.
The microtime(true) test took 1.0222 seconds.
Each test case ran 20 random code order iterations consisting of 283,446 loops for a total of 5,668,920 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 283,446 loops.
- Total difference 10.68 milliseconds for 5,668,920 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.
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);
