Result: Discarded

The test labeled "mt_rand()" was the faster by 0.0224 seconds, (3.817% faster)

mt_rand() 100%
rand() 96.183%

The mt_rand() test took 0.5637 seconds.
The rand() test took 0.586 seconds.


Each test case ran 20 random code order iterations consisting of 142,530 loops for a total of 2,850,600 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.118) milliseconds per 142,530 loops.
  • Total difference 22.37 milliseconds for 2,850,600 loops

The iteration variablity for Code 1 was (5.3618) milliseconds and Code 2 was (3.1386) 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);
