The test labeled "DirectoryIterator()" was the faster by 0.0068 seconds, (1.476% faster)

DirectoryIterator() 100%
glob(GLOB_NOSORT) 98.524%

The DirectoryIterator() test took 0.457 seconds.
The glob(GLOB_NOSORT) test took 0.4639 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 125,306 loops for a total of 2,506,120 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.342) milliseconds per 125,306 loops.
  • Total difference 6.85 milliseconds for 2,506,120 loops

The iteration variablity for Code 1 was (0.5766) milliseconds and Code 2 was (0.5350) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "DirectoryIterator()", was:

$result = array();
foreach (new DirectoryIterator($GLOBALS['basedir'] . '/tests') as $file)
{
	if (!$file->isDot())
	    $result[] = $file->getFilename();
}

The second test, "glob(GLOB_NOSORT)", was:

$result = array();
foreach (glob($GLOBALS['basedir'] . '/tests/*', GLOB_NOSORT) as $file)
{
	if ($file !== '.' && $file !== '..')
		$result[] = $file;
}
