Result: Discarded

The test labeled "rand()" was the faster by 0.0141 seconds, (2.640% faster)

rand() 100%
mt_rand() 97.36%

The rand() test took 0.5214 seconds.
The mt_rand() test took 0.5356 seconds.


Each test case ran 20 random code order iterations consisting of 144,956 loops for a total of 2,899,120 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.707) milliseconds per 144,956 loops.
  • Total difference 14.14 milliseconds for 2,899,120 loops

The iteration variablity for Code 1 was (0.2424) milliseconds and Code 2 was (0.6770) 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);
