Historical ResultsBased on (2) saved test runs, The test labeled "ob_start()" was (on average) the faster by 0.0163 seconds, (1.865% faster)
The ob_start() test took 0.8549 seconds.
The concat test took 0.8712 seconds.
Each test case ran 20 random code order iterations consisting of 210,546 loops for a total of 4,210,910 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 210,546 loops.
- Total difference 16.25 milliseconds for 4,210,910 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, "ob_start()", was:
ob_start(); for ($i = 0; $i < 100; $i++) echo 'Wheat Thins!'; $GLOBALS['dummy'] = ob_get_contents(); ob_end_clean();
The second test, "concat", was:
$value = ''; for ($i = 0; $i < 100; $i++) $value .= 'Wheat Thins!'; $GLOBALS['dummy'] = $value;
