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 (3) saved test runs, The test labeled "class" was (on average) the faster by 0 seconds, (0.004% faster)

class 100%
arrays 99.996%

The class test took 0.7526 seconds.
The arrays test took 0.7526 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 166,809 loops for a total of 3,336,180 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.000) milliseconds per 166,809 loops.
  • Total difference 0.03 milliseconds for 3,336,180 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;
