PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: single class vs. associative arrays

This test creates objects or arrays, and fills them with equivalent data. The array is prefilled with nulls in attempt to be fair.

Run this test again Return to test menu

Result: Discarded

The test labeled "arrays" was the faster by 0.0335 seconds, (4.055% faster)

arrays 100%
class 95.945%

The arrays test took 0.7922 seconds.
The class test took 0.8257 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 205,075 loops for a total of 4,101,500 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.674) milliseconds per 205,075 loops.
  • Total difference 33.48 milliseconds for 4,101,500 loops

The iteration variablity for Code 1 was (7.4221) milliseconds and Code 2 was (4.3400) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "class", was:

/*
class TestClass
{
	var $x, $y, $z;
}
*/

$data = new TestClass();

$data->x = 'test';
$data->y = 1;
$data->z = 5.5;

The second test, "arrays", was:

$data = array(
	'x' => null,
	'y' => null,
	'z' => null,
);

$data['x'] = 'test';
$data['y'] = 1;
$data['z'] = 5.5;
