Historical ResultsBased on (3) saved test runs, The test labeled "time()" was (on average) the faster by 0.0099 seconds, (1.078% faster)
The time() test took 0.9117 seconds.
The microtime(true) test took 0.9216 seconds.
Each test case ran 20 random code order iterations consisting of 242,908 loops for a total of 4,858,167 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 242,908 loops.
- Total difference 9.94 milliseconds for 4,858,167 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);
