Result: Discarded

The test labeled "preg_split()" was the faster by 0.0668 seconds, (5.752% faster)

preg_split() 100%
explode() 94.248%

The preg_split() test took 1.0943 seconds.
The explode() test took 1.1611 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 292,745 loops for a total of 5,854,900 runs.

  • Line execution difference (0.000011) milliseconds.
  • Avg difference (3.339) milliseconds per 292,745 loops.
  • Total difference 66.79 milliseconds for 5,854,900 loops

The iteration variablity for Code 1 was (5.2748) milliseconds and Code 2 was (6.2818) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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

$GLOBALS['dummy2'] = preg_split('~\r\n|\r|\n~', $GLOBALS['dummy']);

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

$GLOBALS['dummy2'] = explode("\n", str_replace(array("\r\n", "\r"), "\n", $GLOBALS['dummy']));
