Historical Results

Based on (6) saved test runs, The test labeled "preg_match()" was (on average) the faster by 0.0069 seconds, (0.980% faster)

preg_match() 100%
strpos() 99.02%

The preg_match() test took 0.6937 seconds.
The strpos() test took 0.7005 seconds.


Each test case ran 20 random code order iterations consisting of 178,992 loops for a total of 3,579,843 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 178,992 loops.
  • Total difference 6.86 milliseconds for 3,579,843 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.


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'], '') !== false)
	$GLOBALS['dummy2'] = 42;
