Each test case ran 20 random code order iterations consisting of 233,373 loops for a total of 4,667,460 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.777) milliseconds per 233,373 loops.
  • Total difference 35.55 milliseconds for 4,667,460 loops

The iteration variablity for Code 1 was (7.4859) milliseconds and Code 2 was (7.4733) milliseconds. The lower and the closer together there values are the more accurate the results are.


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

$lines = file('supplement/');
foreach ($lines as $line)
	$GLOBALS['dummy2'] = rtrim($line);

The second test, "file_get_contents()", was:

$lines = explode("\n", str_replace(array("\r\n", "\r"), "\n", file_get_contents('supplement/')));
foreach ($lines as $line)
	$GLOBALS['dummy2'] = $line;
