Result: Discarded
The test labeled "not" was the faster by 0.0017 seconds, (0.157% faster)
The not test took 1.0657 seconds.
The ob_start() test took 1.0674 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 288,367 loops for a total of 5,767,340 runs.
- Line execution difference (0.000000) milliseconds.
- Avg difference (0.084) milliseconds per 288,367 loops.
- Total difference 1.67 milliseconds for 5,767,340 loops
The iteration variablity for Code 1 was (4.4104) milliseconds and Code 2 was (3.8006) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "ob_start()", was:
ob_start(); for ($i = 0; $i < 20; $i++) $GLOBALS['dummy2'] = $i * 2; ob_end_clean();
The second test, "not", was:
for ($i = 0; $i < 20; $i++) $GLOBALS['dummy2'] = $i * 2;
