Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 135,322 loops for a total of 2,706,440 runs.

  • Line execution difference (0.000020) milliseconds.
  • Avg difference (2.678) milliseconds per 135,322 loops.
  • Total difference 53.55 milliseconds for 2,706,440 loops

The iteration variablity for Code 1 was (7.3204) milliseconds and Code 2 was (8.5418) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

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

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

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