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 0.0816 seconds, (5.683% faster)

class 100%
arrays 94.317%

The class test took 1.3542 seconds.
The arrays test took 1.4358 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 280,133 loops for a total of 5,602,660 runs.

  • Line execution difference (0.000015) milliseconds.
  • Avg difference (4.079) milliseconds per 280,133 loops.
  • Total difference 81.59 milliseconds for 5,602,660 loops

The iteration variablity for Code 1 was (12.9416) milliseconds and Code 2 was (15.4934) 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;
