Historical Results

Based on (1) saved test runs, The test labeled "==" was (on average) the faster by 0.0286 seconds, (2.475% faster)

== 100%
=== 97.525%

The == test took 1.1276 seconds.
The === test took 1.1563 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 271,695 loops for a total of 5,433,900 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 271,695 loops.
  • Total difference 28.61 milliseconds for 5,433,900 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'] = $GLOBALS['dummy1'] === $GLOBALS['dummy2'];
