PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: == vs. === (pass, same types)

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "==" was the faster by 0.0859 seconds, (8.048% faster)

== 100%
=== 91.952%

The == test took 0.981 seconds.
The === test took 1.0669 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 212,477 loops for a total of 4,249,540 runs.

  • Line execution difference (0.000020) milliseconds.
  • Avg difference (4.293) milliseconds per 212,477 loops.
  • Total difference 85.86 milliseconds for 4,249,540 loops

The iteration variablity for Code 1 was (11.5987) milliseconds and Code 2 was (12.0983) 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'];
