Historical ResultsBased on (4) saved test runs, The test labeled "global" was (on average) the faster by 0.0108 seconds, (1.198% faster)
The global test took 0.8888 seconds.
The local test took 0.8996 seconds.
Each test case ran 20 random code order iterations consisting of 180,641 loops for a total of 3,612,815 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 180,641 loops.
- Total difference 10.78 milliseconds for 3,612,815 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;
