Historical Results

Based on (3) saved test runs, The test labeled "sprintf()" was (on average) the faster by 0.0035 seconds, (0.597% faster)

sprintf() 100%
commas 99.403%

The sprintf() test took 0.587 seconds.
The commas test took 0.5906 seconds.


Each test case ran 20 random code order iterations consisting of 147,986 loops for a total of 2,959,720 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 147,986 loops.
  • Total difference 3.52 milliseconds for 2,959,720 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']);
