The test labeled "rand()" was the faster by 0.0424 seconds, (7.265% faster)

rand() 100%
mt_rand() 92.735%

The rand() test took 0.5408 seconds.
The mt_rand() test took 0.5832 seconds.


Each test case ran 20 random code order iterations consisting of 133,237 loops for a total of 2,664,740 runs.

  • Line execution difference (0.000016) milliseconds.
  • Avg difference (2.118) milliseconds per 133,237 loops.
  • Total difference 42.37 milliseconds for 2,664,740 loops

The iteration variablity for Code 1 was (1.8768) milliseconds and Code 2 was (2.9475) milliseconds. The lower and the closer together there values are the more accurate the results are.


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

$GLOBALS['dummy'] = rand(0, 1000);

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

$GLOBALS['dummy'] = mt_rand(0, 1000);
