Historical Results

Based on (5) saved test runs, The test labeled "commas" was (on average) the faster by 0.023 seconds, (2.648% faster)

commas 100%
interpolation 97.352%

The commas test took 0.8457 seconds.
The interpolation test took 0.8687 seconds.


Each test case ran 20 random code order iterations consisting of 207,142 loops for a total of 4,142,836 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.000) milliseconds per 207,142 loops.
  • Total difference 23.00 milliseconds for 4,142,836 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 ";
