Result: Discarded

The test labeled "DirectoryIterator()" was the faster by 0.0226 seconds, (2.689% faster)

DirectoryIterator() 100%
glob(GLOB_NOSORT) 97.311%

The DirectoryIterator() test took 0.8164 seconds.
The glob(GLOB_NOSORT) test took 0.839 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 212,531 loops for a total of 4,250,620 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.128) milliseconds per 212,531 loops.
  • Total difference 22.56 milliseconds for 4,250,620 loops

The iteration variablity for Code 1 was (3.1706) milliseconds and Code 2 was (2.4716) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

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

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

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