The test labeled "$array[0]" was the faster by 0.0209 seconds, (1.893% faster)
The $array[0] test took 1.0815 seconds.
The list ($v) = test took 1.1024 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 283,734 loops for a total of 5,674,680 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (1.044) milliseconds per 283,734 loops.
- Total difference 20.87 milliseconds for 5,674,680 loops
The iteration variablity for Code 1 was (5.4245) milliseconds and Code 2 was (3.3339) 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];
