Result: Discarded

The test labeled "sprintf()" was the faster by 0.0547 seconds, (6.621% faster)

sprintf() 100%
commas 93.379%

The sprintf() test took 0.7722 seconds.
The commas test took 0.8269 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 134,003 loops for a total of 2,680,060 runs.

  • Line execution difference (0.000020) milliseconds.
  • Avg difference (2.737) milliseconds per 134,003 loops.
  • Total difference 54.75 milliseconds for 2,680,060 loops

The iteration variablity for Code 1 was (6.9908) milliseconds and Code 2 was (6.7814) 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, "sprintf()", was:

echo sprintf('%s test %s%s test ', $GLOBALS['x'], $GLOBALS['y'], $GLOBALS['z']);
