Historical ResultsBased on (1) saved test runs, The test labeled "time()" was (on average) the faster by 0.0707 seconds, (5.888% faster)
The time() test took 1.1306 seconds.
The microtime(true) test took 1.2014 seconds.
Each test case ran 20 random code order iterations consisting of 289,611 loops for a total of 5,792,220 runs.
- Line execution difference (0.000012) milliseconds.
- Avg difference (0.000) milliseconds per 289,611 loops.
- Total difference 70.73 milliseconds for 5,792,220 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);
