The commas test took 1.1539 seconds.
The interpolation test took 1.3143 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 279,946 loops for a total of 5,598,920 runs.
- Line execution difference (0.000029) milliseconds.
- Avg difference (8.020) milliseconds per 279,946 loops.
- Total difference 160.40 milliseconds for 5,598,920 loops
The iteration variablity for Code 1 was (4.2844) milliseconds and Code 2 was (10.1471) 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 ";
