Result: Discarded

The test labeled "commas" was the faster by 0.0014 seconds, (0.238% faster)

commas 100%
concat 99.762%

The commas test took 0.5693 seconds.
The concat test took 0.5707 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 126,936 loops for a total of 2,538,720 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.068) milliseconds per 126,936 loops.
  • Total difference 1.36 milliseconds for 2,538,720 loops

The iteration variablity for Code 1 was (5.1821) milliseconds and Code 2 was (4.0795) 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 ';
