Result: Discarded

The test labeled "==" was the faster by 0.0429 seconds, (6.321% faster)

== 100%
=== 93.679%

The == test took 0.6361 seconds.
The === test took 0.679 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 138,311 loops for a total of 2,766,220 runs.

  • Line execution difference (0.000016) milliseconds.
  • Avg difference (2.146) milliseconds per 138,311 loops.
  • Total difference 42.92 milliseconds for 2,766,220 loops

The iteration variablity for Code 1 was (5.5492) milliseconds and Code 2 was (7.5619) 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'];
