The == null test took 0.6779 seconds.
The === null test took 0.6846 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 156,460 loops for a total of 3,129,200 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.338) milliseconds per 156,460 loops.
- Total difference 6.76 milliseconds for 3,129,200 loops
The iteration variablity for Code 1 was (7.2243) milliseconds and Code 2 was (4.3048) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "=== null", was:
for ($j = 0; $j < 100; $j++)
{
$GLOBALS['dummy3'] = $GLOBALS['dummy1'] === null;
$GLOBALS['dummy3'] += $GLOBALS['dummy2'] === null;
}
The second test, "== null", was:
for ($j = 0; $j < 100; $j++)
{
$GLOBALS['dummy3'] = $GLOBALS['dummy1'] == null;
$GLOBALS['dummy3'] += $GLOBALS['dummy2'] == null;
}
