Result: Discarded

The test labeled "==" was the faster by 0.0707 seconds, (6.224% faster)

== 100%
=== 93.776%

The == test took 1.0644 seconds.
The === test took 1.1351 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 272,490 loops for a total of 5,449,800 runs.

  • Line execution difference (0.000013) milliseconds.
  • Avg difference (3.533) milliseconds per 272,490 loops.
  • Total difference 70.65 milliseconds for 5,449,800 loops

The iteration variablity for Code 1 was (6.9459) milliseconds and Code 2 was (8.5368) 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'] = $GLOBALS['dummy1'] === $GLOBALS['dummy2'];
