Historical Results

Based on (2) saved test runs, The test labeled "strpos()" was (on average) the faster by 0.0034 seconds, (0.345% faster)

strpos() 100%
preg_match() 99.655%

The strpos() test took 0.9752 seconds.
The preg_match() test took 0.9785 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 205,596 loops for a total of 4,111,910 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 205,596 loops.
  • Total difference 3.38 milliseconds for 4,111,910 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;
