Result: Discarded

The test labeled "==" was the faster by 0.0506 seconds, (4.664% faster)

== 100%
=== 95.336%

The == test took 1.0351 seconds.
The === test took 1.0857 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 289,412 loops for a total of 5,788,240 runs.

  • Line execution difference (0.000009) milliseconds.
  • Avg difference (2.532) milliseconds per 289,412 loops.
  • Total difference 50.64 milliseconds for 5,788,240 loops

The iteration variablity for Code 1 was (2.1584) milliseconds and Code 2 was (4.0555) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "==", was:

for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy3'] = $GLOBALS['dummy1'] == $GLOBALS['dummy2'];

The second test, "===", was:

for ($j = 0; $j < 100; $j++)
	$GLOBALS['dummy3'] = (int) $GLOBALS['dummy1'] === (int) $GLOBALS['dummy2'];
