Historical ResultsBased on (1) saved test runs, The test labeled "interpolation" was (on average) the faster by 0.0027 seconds, (0.313% faster)
The interpolation test took 0.8727 seconds.
The commas test took 0.8754 seconds.
Each test case ran 20 random code order iterations consisting of 131,000 loops for a total of 2,620,000 runs.
- Line execution difference (0.000001) milliseconds.
- Avg difference (0.000) milliseconds per 131,000 loops.
- Total difference 2.74 milliseconds for 2,620,000 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 ";
