The test labeled "==" was the faster by 0.0215 seconds, (2.566% faster)

== 100%
=== 97.434%

The == test took 0.8176 seconds.
The === test took 0.8391 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 130,979 loops for a total of 2,619,580 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.076) milliseconds per 130,979 loops.
  • Total difference 21.53 milliseconds for 2,619,580 loops

The iteration variablity for Code 1 was (9.5444) milliseconds and Code 2 was (9.3956) 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'];
