The test labeled "$array[] =" was the faster by 0.0131 seconds, (1.250% faster)
The $array[] = test took 1.0366 seconds.
The array_push() test took 1.0497 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 284,504 loops for a total of 5,690,080 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.656) milliseconds per 284,504 loops.
- Total difference 13.12 milliseconds for 5,690,080 loops
The iteration variablity for Code 1 was (4.0514) milliseconds and Code 2 was (1.8072) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "array_push()", was:
$array = array(); for ($n = 0; $n < 8; $n++) { for ($i = 0; $i < 50; $i++) array_push($array, $i); }
The second test, "$array[] =", was:
$array = array(); for ($n = 0; $n < 8; $n++) { for ($i = 0; $i < 50; $i++) $array[] = $i; }
