The test labeled "list ($v) =" was the faster by 0.0307 seconds, (4.276% faster)
The list ($v) = test took 0.6881 seconds.
The $array[0] test took 0.7188 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 165,635 loops for a total of 3,312,700 runs.
- Line execution difference (0.000009) milliseconds.
- Avg difference (1.537) milliseconds per 165,635 loops.
- Total difference 30.74 milliseconds for 3,312,700 loops
The iteration variablity for Code 1 was (2.1617) milliseconds and Code 2 was (2.6031) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "list ($v) =", was:
list ($v) = $GLOBALS['array'];
The second test, "$array[0]", was:
$v = $GLOBALS['array'][0];
