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.

The test labeled "class" was the faster by 0.0349 seconds, (3.745% faster)

class 100%
arrays 96.255%

The class test took 0.8961 seconds.
The arrays test took 0.931 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 132,952 loops for a total of 2,659,040 runs.

  • Line execution difference (0.000013) milliseconds.
  • Avg difference (1.743) milliseconds per 132,952 loops.
  • Total difference 34.87 milliseconds for 2,659,040 loops

The iteration variablity for Code 1 was (10.1672) milliseconds and Code 2 was (10.7482) 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;
