Historical ResultsBased on (4) saved test runs, The test labeled "commas" was (on average) the faster by 0.009 seconds, (1.071% faster)
The commas test took 0.8344 seconds.
The sprintf() test took 0.8434 seconds.
Each test case ran 20 random code order iterations consisting of 197,733 loops for a total of 3,954,655 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 197,733 loops.
- Total difference 9.03 milliseconds for 3,954,655 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']);
