Result: Discarded
The test labeled "static" was the faster by 0.033 seconds, (3.031% faster)
The static test took 1.0544 seconds.
The global test took 1.0874 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 286,545 loops for a total of 5,730,900 runs.
- Line execution difference (0.000006) milliseconds.
- Avg difference (1.648) milliseconds per 286,545 loops.
- Total difference 32.96 milliseconds for 5,730,900 loops
The iteration variablity for Code 1 was (5.4057) milliseconds and Code 2 was (2.1761) 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);
