Test: list vs. [0]
These tests use an array with many values in it.
Run this test again Return to test menuResult: Discarded
The test labeled "$array[0]" was the faster by 0.0754 seconds, (5.885% faster)
The $array[0] test took 1.2063 seconds.
The list ($v) = test took 1.2818 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 287,428 loops for a total of 5,748,560 runs.
- Line execution difference (0.000013) milliseconds.
- Avg difference (3.771) milliseconds per 287,428 loops.
- Total difference 75.43 milliseconds for 5,748,560 loops
The iteration variablity for Code 1 was (13.6782) milliseconds and Code 2 was (5.5867) 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];
