Each test case ran 20 random code order iterations consisting of 133,438 loops for a total of 2,668,760 runs.

  • Line execution difference (0.000012) milliseconds.
  • Avg difference (1.556) milliseconds per 133,438 loops.
  • Total difference 31.13 milliseconds for 2,668,760 loops

The iteration variablity for Code 1 was (5.1819) milliseconds and Code 2 was (4.1387) 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;
