Historical ResultsBased on (2) saved test runs, The test labeled "global" was (on average) the faster by 0.0028 seconds, (0.517% faster)
The global test took 0.535 seconds.
The local test took 0.5378 seconds.
Each test case ran 20 random code order iterations consisting of 144,561 loops for a total of 2,891,220 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 144,561 loops.
- Total difference 2.78 milliseconds for 2,891,220 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, "global", was:
global $dummy; for ($i = 0; $i < 100; $i++) $dummy = $i;
The second test, "local", was:
$dummy = null; for ($i = 0; $i < 100; $i++) $dummy = $i;
