Result: DiscardedThe test labeled "concat" was the faster by 0.0127 seconds, (1.108% faster)
The concat test took 1.1308 seconds.
The commas test took 1.1435 seconds.
Each test case ran 20 random code order iterations consisting of 294,130 loops for a total of 5,882,600 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.633) milliseconds per 294,130 loops.
- Total difference 12.67 milliseconds for 5,882,600 loops
The iteration variablity for Code 1 was (6.6107) milliseconds and Code 2 was (5.2833) 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 ';
