Result: Discarded
The test labeled "commas" was the faster by 0.005 seconds, (0.931% faster)
The commas test took 0.5367 seconds.
The concat test took 0.5417 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 137,450 loops for a total of 2,749,000 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.252) milliseconds per 137,450 loops.
- Total difference 5.04 milliseconds for 2,749,000 loops
The iteration variablity for Code 1 was (3.4936) milliseconds and Code 2 was (2.1997) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
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 ';
