The commas test took 0.5533 seconds.
The interpolation test took 0.5984 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 129,085 loops for a total of 2,581,700 runs.
- Line execution difference (0.000017) milliseconds.
- Avg difference (2.253) milliseconds per 129,085 loops.
- Total difference 45.07 milliseconds for 2,581,700 loops
The iteration variablity for Code 1 was (3.8491) milliseconds and Code 2 was (3.6866) 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'], $GLOBALS['z'], ' test ';
The second test, "interpolation", was:
echo "$GLOBALS[x] test $GLOBALS[y]$GLOBALS[z] test ";
