Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 113,597 loops for a total of 2,271,940 runs.

Line execution difference (0.000020) milliseconds.
Avg difference (2.250) milliseconds per 113,597 loops.
Total difference 45.00 milliseconds for 2,271,940 loops

The iteration variablity for Code 1 was (4.3707) milliseconds and Code 2 was (0.9724) 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, "concat", was:

echo $GLOBALS['x'] . ' test ' . $GLOBALS['y'] . $GLOBALS['z'] . ' test ';
