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.

Historical Results

Based on (1) saved test runs, The test labeled "class" was (on average) the faster by 0.007 seconds, (1.335% faster)

class 100%
arrays 98.665%

The class test took 0.5157 seconds.
The arrays test took 0.5227 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 141,020 loops for a total of 2,820,400 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 141,020 loops.
  • Total difference 6.98 milliseconds for 2,820,400 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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;
