Historical ResultsBased on (2) saved test runs, The test labeled "interpolation" was (on average) the faster by 0.0046 seconds, (0.507% faster)
The interpolation test took 0.9093 seconds.
The commas test took 0.914 seconds.
Each test case ran 20 random code order iterations consisting of 211,158 loops for a total of 4,223,150 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 211,158 loops.
- Total difference 4.64 milliseconds for 4,223,150 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 ";
