Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 229,385 loops for a total of 4,587,700 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.350) milliseconds per 229,385 loops.
  • Total difference 6.99 milliseconds for 4,587,700 loops

The iteration variablity for Code 1 was (2.8020) milliseconds and Code 2 was (1.6685) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

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 ";
