The test labeled "array_walk()" was the faster by 0.0251 seconds, (2.310% faster)
The array_walk() test took 1.0605 seconds.
The array_walk_recursive() test took 1.0856 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 210,214 loops for a total of 4,204,280 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.254) milliseconds per 210,214 loops.
- Total difference 25.08 milliseconds for 4,204,280 loops
The iteration variablity for Code 1 was (9.7476) milliseconds and Code 2 was (11.7176) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "array_walk()", was:
/* function foo_manual(&$v) { if (is_array($v)) array_walk($v, 'foo_manual'); else $v++; } */ array_walk($GLOBALS['dummy'], 'foo_manual');
The second test, "array_walk_recursive()", was:
/* function foo_auto(&$v) { $v++; } */ array_walk_recursive($GLOBALS['dummy'], 'foo_auto');
