The test labeled "list ($v) =" was the faster by 0.0045 seconds, (0.405% faster)
The list ($v) = test took 1.1163 seconds.
The $array[0] test took 1.1209 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 296,994 loops for a total of 5,939,880 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.227) milliseconds per 296,994 loops.
- Total difference 4.53 milliseconds for 5,939,880 loops
The iteration variablity for Code 1 was (4.9617) milliseconds and Code 2 was (3.4911) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "list ($v) =", was:
list ($v) = $GLOBALS['array'];
The second test, "$array[0]", was:
$v = $GLOBALS['array'][0];
