The test labeled "commas" was the faster by 0.019 seconds, (1.715% faster)

commas 100%
sprintf() 98.285%

The commas test took 1.0868 seconds.
The sprintf() test took 1.1058 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 285,715 loops for a total of 5,714,300 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.948) milliseconds per 285,715 loops.
  • Total difference 18.96 milliseconds for 5,714,300 loops

The iteration variablity for Code 1 was (1.7557) milliseconds and Code 2 was (1.8519) 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']);
