Historical ResultsBased on (2) saved test runs, The test labeled "strpos()" was (on average) the faster by 0.0034 seconds, (0.345% faster)
The strpos() test took 0.9752 seconds.
The preg_match() test took 0.9785 seconds.
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.
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;
