Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 246,542 loops for a total of 4,930,840 runs.

Line execution difference (0.000006) milliseconds.
Avg difference (1.424) milliseconds per 246,542 loops.
Total difference 28.49 milliseconds for 4,930,840 loops

The iteration variablity for Code 1 was (2.6847) milliseconds and Code 2 was (2.8647) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "@define()", was:

@define('CONSTANT', $GLOBALS['dummy']);
