Result: Discarded

The test labeled "interpolation" was the faster by 0.0104 seconds, (2.056% faster)

interpolation 100%
commas 97.944%

The interpolation test took 0.4942 seconds.
The commas test took 0.5046 seconds.


Each test case ran 20 random code order iterations consisting of 130,653 loops for a total of 2,613,060 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.519) milliseconds per 130,653 loops.
  • Total difference 10.37 milliseconds for 2,613,060 loops

The iteration variablity for Code 1 was (2.5726) milliseconds and Code 2 was (1.5731) 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 ";
