The test labeled "list ($v) =" was the faster by 0.0331 seconds, (4.991% faster)
The list ($v) = test took 0.63 seconds.
The $array[0] test took 0.6631 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 132,500 loops for a total of 2,650,000 runs.
- Line execution difference (0.000012) milliseconds.
- Avg difference (1.655) milliseconds per 132,500 loops.
- Total difference 33.09 milliseconds for 2,650,000 loops
The iteration variablity for Code 1 was (7.6800) milliseconds and Code 2 was (8.1746) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "list ($v) =", was:
list ($v) = $GLOBALS['array'];
The second test, "$array[0]", was:
$v = $GLOBALS['array'][0];
