Result: DiscardedThe test labeled "concat" was the faster by 0.045 seconds, (9.317% faster)
The concat test took 0.438 seconds.
The commas test took 0.483 seconds.
Each test case ran 20 random code order iterations consisting of 113,597 loops for a total of 2,271,940 runs.
- Line execution difference (0.000020) milliseconds.
- Avg difference (2.250) milliseconds per 113,597 loops.
- Total difference 45.00 milliseconds for 2,271,940 loops
The iteration variablity for Code 1 was (4.3707) milliseconds and Code 2 was (0.9724) 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 ';
