The test labeled "== null" was the faster by 0.0084 seconds, (1.869% faster)
The == null test took 0.4409 seconds.
The === null test took 0.4493 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 116,282 loops for a total of 2,325,640 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.420) milliseconds per 116,282 loops.
- Total difference 8.40 milliseconds for 2,325,640 loops
The iteration variablity for Code 1 was (2.5298) milliseconds and Code 2 was (1.3364) 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;
}
