The test labeled "fcall" was the faster by 0.0119 seconds, (1.988% faster)
The fcall test took 0.5847 seconds.
The call_user_func_array() test took 0.5966 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 131,205 loops for a total of 2,624,100 runs.
- Line execution difference (0.000005) milliseconds.
- Avg difference (0.593) milliseconds per 131,205 loops.
- Total difference 11.86 milliseconds for 2,624,100 loops
The iteration variablity for Code 1 was (2.3359) milliseconds and Code 2 was (2.2351) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "fcall", was:
/*
function do_something($i)
{
for ($i = 0; $i < 20; $i++)
$GLOBALS['dummy'] + $i;
}
*/
do_something(74);
The second test, "call_user_func_array()", was:
/*
function do_something($i)
{
for ($i = 0; $i < 20; $i++)
$GLOBALS['dummy'] + $i;
}
*/
call_user_func_array('do_something', array(74));
