The test labeled "$array[0]" was the faster by 0.0042 seconds, (0.697% faster)
The $array[0] test took 0.5981 seconds.
The list ($v) = test took 0.6023 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 144,706 loops for a total of 2,894,120 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.210) milliseconds per 144,706 loops.
- Total difference 4.20 milliseconds for 2,894,120 loops
The iteration variablity for Code 1 was (1.2875) milliseconds and Code 2 was (1.1206) 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];
