Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 127,797 loops for a total of 2,555,940 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (0.000) milliseconds per 127,797 loops.
  • Total difference 19.40 milliseconds for 2,555,940 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

if (preg_match('~http://www\.google\.com/~', $GLOBALS['dummy']) != 0)
	$GLOBALS['dummy2'] = 42;

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

if (strpos($GLOBALS['dummy'], 'http://wwww.google.com/') !== false)
	$GLOBALS['dummy2'] = 42;
