Historical Results

Based on (2) saved test runs, The test labeled "sprintf()" was (on average) the faster by 0.0054 seconds, (0.584% faster)

sprintf() 100%
commas 99.416%

The sprintf() test took 0.9226 seconds.
The commas test took 0.928 seconds.


Each test case ran 20 random code order iterations consisting of 199,987 loops for a total of 3,999,730 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 199,987 loops.
  • Total difference 5.42 milliseconds for 3,999,730 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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']);
