Result: Discarded
The test labeled "static" was the faster by 0.0179 seconds, (2.770% faster)
The static test took 0.6276 seconds.
The global test took 0.6455 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 134,551 loops for a total of 2,691,020 runs.
- Line execution difference (0.000007) milliseconds.
- Avg difference (0.894) milliseconds per 134,551 loops.
- Total difference 17.88 milliseconds for 2,691,020 loops
The iteration variablity for Code 1 was (7.5186) milliseconds and Code 2 was (6.0359) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "global", was:
/*
function foo_global($i)
{
global $dummy;
$dummy = $i;
}
*/
for ($i = 0; $i < 100; $i++)
foo_global($i);
The second test, "static", was:
/*
function foo_static($i)
{
static $dummy = null;
$dummy = $i;
}
*/
for ($i = 0; $i < 100; $i++)
foo_static($i);
