Historical ResultsBased on (2) saved test runs, The test labeled "commas" was (on average) the faster by 0.0015 seconds, (0.274% faster)
The commas test took 0.5446 seconds.
The concat test took 0.5461 seconds.
Each test case ran 20 random code order iterations consisting of 148,459 loops for a total of 2,969,170 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 148,459 loops.
- Total difference 1.50 milliseconds for 2,969,170 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, "concat", was:
echo $GLOBALS['x'] . ' test ' . $GLOBALS['y'] . $GLOBALS['z'] . ' test ';
