Result: Discarded

The test labeled "===" was the faster by 0.0426 seconds, (4.122% faster)

=== 100%
== 95.878%

The === test took 0.9912 seconds.
The == test took 1.0338 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 279,434 loops for a total of 5,588,680 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (2.131) milliseconds per 279,434 loops.
  • Total difference 42.61 milliseconds for 5,588,680 loops

The iteration variablity for Code 1 was (5.3021) milliseconds and Code 2 was (1.7627) 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'];
