Based on (4) saved test runs, The test labeled "array_walk()" was (on average) the faster by 0.0134 seconds, (2.193% faster)
The array_walk() test took 0.5988 seconds.
The array_walk_recursive() test took 0.6122 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 144,918 loops for a total of 2,898,365 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.000) milliseconds per 144,918 loops.
- Total difference 13.43 milliseconds for 2,898,365 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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');
