Historical ResultsBased on (3) saved test runs, The test labeled "commas" was (on average) the faster by 0.0138 seconds, (1.369% faster)
The commas test took 0.992 seconds.
The interpolation test took 1.0058 seconds.
Each test case ran 20 random code order iterations consisting of 278,822 loops for a total of 5,576,447 runs.
- Line execution difference (0.000002) milliseconds.
- Avg difference (0.000) milliseconds per 278,822 loops.
- Total difference 13.76 milliseconds for 5,576,447 loops
The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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'], $GLOBALS['z'], ' test ';
The second test, "interpolation", was:
echo "$GLOBALS[x] test $GLOBALS[y]$GLOBALS[z] test ";
