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 0.0143 seconds, (1.323% faster)

== 100%
=== 98.677%

The == test took 1.0686 seconds.
The === test took 1.0829 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 254,856 loops for a total of 5,097,120 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.716) milliseconds per 254,856 loops.
  • Total difference 14.33 milliseconds for 5,097,120 loops

The iteration variablity for Code 1 was (7.1397) milliseconds and Code 2 was (6.6475) 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'];
