PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: == vs. === (fail, different types)

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "===" was the faster by 0.0017 seconds, (0.261% faster)

=== 100%
== 99.739%

The === test took 0.6639 seconds.
The == test took 0.6656 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 129,784 loops for a total of 2,595,680 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.087) milliseconds per 129,784 loops.
  • Total difference 1.74 milliseconds for 2,595,680 loops

The iteration variablity for Code 1 was (7.1074) milliseconds and Code 2 was (6.1014) 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'];
