Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 271,388 loops for a total of 5,427,760 runs.

Line execution difference (0.000002) milliseconds.
Avg difference (0.608) milliseconds per 271,388 loops.
Total difference 12.15 milliseconds for 5,427,760 loops

The iteration variablity for Code 1 was (1.2847) milliseconds and Code 2 was (1.3461) 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 ';
