Result: DiscardedThe test labeled "commas" was the faster by 0.006 seconds, (0.578% faster)
The commas test took 1.0375 seconds.
The concat test took 1.0435 seconds.
Each test case ran 20 random code order iterations consisting of 272,048 loops for a total of 5,440,960 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.302) milliseconds per 272,048 loops.
- Total difference 6.03 milliseconds for 5,440,960 loops
The iteration variablity for Code 1 was (1.7036) milliseconds and Code 2 was (2.0329) 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 ';
