Historical Results

Based on (1) saved test runs, The test labeled "commas" was (on average) the faster by 0.0088 seconds, (0.835% faster)

commas 100%
sprintf() 99.165%

The commas test took 1.0505 seconds.
The sprintf() test took 1.0593 seconds.


Each test case ran 20 random code order iterations consisting of 282,873 loops for a total of 5,657,460 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 282,873 loops.
  • Total difference 8.85 milliseconds for 5,657,460 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']);
