Result: Discarded

The test labeled "sprintf()" was the faster by 0.0355 seconds, (2.882% faster)

sprintf() 100%
commas 97.118%

The sprintf() test took 1.1947 seconds.
The commas test took 1.2302 seconds.


Each test case ran 20 random code order iterations consisting of 280,884 loops for a total of 5,617,680 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (1.773) milliseconds per 280,884 loops.
  • Total difference 35.46 milliseconds for 5,617,680 loops

The iteration variablity for Code 1 was (7.3911) milliseconds and Code 2 was (5.9669) 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']);
