The test labeled "list ($v) =" was the faster by 0.0311 seconds, (3.140% faster)
The list ($v) = test took 0.9579 seconds.
The $array[0] test took 0.9889 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 229,573 loops for a total of 4,591,460 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (1.553) milliseconds per 229,573 loops.
- Total difference 31.05 milliseconds for 4,591,460 loops
The iteration variablity for Code 1 was (4.4025) milliseconds and Code 2 was (5.8494) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "list ($v) =", was:
list ($v) = $GLOBALS['array'];
The second test, "$array[0]", was:
$v = $GLOBALS['array'][0];
