Historical Results

Based on (1) saved test runs, The test labeled "===" was (on average) the faster by 0.0131 seconds, (1.828% faster)

=== 100%
== 98.172%

The === test took 0.7055 seconds.
The == test took 0.7186 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 132,479 loops for a total of 2,649,580 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 132,479 loops.
  • Total difference 13.14 milliseconds for 2,649,580 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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'];
