Result: Discarded

The test labeled "commas" was the faster by 0.1092 seconds, (9.406% faster)

commas 100%
sprintf() 90.594%

The commas test took 1.0514 seconds.
The sprintf() test took 1.1606 seconds.


Each test case ran 20 random code order iterations consisting of 251,155 loops for a total of 5,023,100 runs.

  • Line execution difference (0.000022) milliseconds.
  • Avg difference (5.458) milliseconds per 251,155 loops.
  • Total difference 109.16 milliseconds for 5,023,100 loops

The iteration variablity for Code 1 was (6.7496) milliseconds and Code 2 was (11.0105) 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']);
