The commas test took 0.49 seconds.
The concat test took 0.5113 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 134,551 loops for a total of 2,691,020 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.066) milliseconds per 134,551 loops.
  • Total difference 21.33 milliseconds for 2,691,020 loops

The iteration variablity for Code 1 was (1.4384) milliseconds and Code 2 was (2.2327) 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 ';
