Historical ResultsBased on (2) saved test runs, The test labeled "global" was (on average) the faster by 0.0111 seconds, (1.435% faster)
The global test took 0.7613 seconds.
The local test took 0.7723 seconds.
Each test case ran 20 random code order iterations consisting of 216,688 loops for a total of 4,333,750 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.000) milliseconds per 216,688 loops.
- Total difference 11.08 milliseconds for 4,333,750 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;
