No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "sprintf()" was the faster by 0.0286 seconds, (1.789% faster)

sprintf() 100%
commas 98.211%

The sprintf() test took 1.5718 seconds.
The commas test took 1.6005 seconds.


Each test case ran 20 random code order iterations consisting of 293,770 loops for a total of 5,875,400 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.432) milliseconds per 293,770 loops.
  • Total difference 28.64 milliseconds for 5,875,400 loops

The iteration variablity for Code 1 was (31.1824) milliseconds and Code 2 was (32.0401) milliseconds. The lower and the closer together there values are the more accurate the results are.


The first test, "commas", was:

echo $GLOBALS['x'], ' test ', $GLOBALS['y'], $GLOBALS['z'], ' test ';

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

echo sprintf('%s test %s%s test ', $GLOBALS['x'], $GLOBALS['y'], $GLOBALS['z']);
