The test labeled "arrays" was the faster by 0.071 seconds, (6.273% faster)

arrays 100%
class 93.727%

The arrays test took 1.0614 seconds.
The class test took 1.1324 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 272,933 loops for a total of 5,458,660 runs.

  • Line execution difference (0.000013) milliseconds.
  • Avg difference (3.552) milliseconds per 272,933 loops.
  • Total difference 71.04 milliseconds for 5,458,660 loops

The iteration variablity for Code 1 was (8.3767) milliseconds and Code 2 was (4.2593) 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;
