Result: Discarded

The test labeled "preg_match()" was the faster by 0.0849 seconds, (7.547% faster)

preg_match() 100%
strpos() 92.453%

The preg_match() test took 1.0402 seconds.
The strpos() test took 1.1252 seconds.


Each test case ran 20 random code order iterations consisting of 271,212 loops for a total of 5,424,240 runs.

  • Line execution difference (0.000016) milliseconds.
  • Avg difference (4.246) milliseconds per 271,212 loops.
  • Total difference 84.92 milliseconds for 5,424,240 loops

The iteration variablity for Code 1 was (3.2106) milliseconds and Code 2 was (9.0720) 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;
