Result: Discarded

The test labeled "sprintf()" was the faster by 0.0695 seconds, (5.679% faster)

sprintf() 100%
commas 94.321%

The sprintf() test took 1.154 seconds.
The commas test took 1.2234 seconds.


Each test case ran 20 random code order iterations consisting of 275,352 loops for a total of 5,507,040 runs.

  • Line execution difference (0.000013) milliseconds.
  • Avg difference (3.474) milliseconds per 275,352 loops.
  • Total difference 69.48 milliseconds for 5,507,040 loops

The iteration variablity for Code 1 was (9.5890) milliseconds and Code 2 was (4.6781) milliseconds. The lower and the closer together there values are the more accurate the results are.


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']);
