The test labeled "commas" was the faster by 0.0171 seconds, (2.613% faster)

commas 100%
sprintf() 97.387%

The commas test took 0.6368 seconds.
The sprintf() test took 0.6539 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 148,418 loops for a total of 2,968,360 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.854) milliseconds per 148,418 loops.
  • Total difference 17.08 milliseconds for 2,968,360 loops

The iteration variablity for Code 1 was (4.6183) milliseconds and Code 2 was (4.6028) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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']);
