Result: Discarded
The test labeled "global" was the faster by 0.0236 seconds, (3.617% faster)
The global test took 0.6284 seconds.
The static test took 0.652 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 114,833 loops for a total of 2,296,660 runs.
- Line execution difference (0.000010) milliseconds.
- Avg difference (1.179) milliseconds per 114,833 loops.
- Total difference 23.58 milliseconds for 2,296,660 loops
The iteration variablity for Code 1 was (8.7867) milliseconds and Code 2 was (9.4319) 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);
