No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "commas" was the faster by 0.0673 seconds, (7.961% faster)

commas 100%
sprintf() 92.039%

The commas test took 0.778 seconds.
The sprintf() test took 0.8453 seconds.


Each test case ran 20 random code order iterations consisting of 217,377 loops for a total of 4,347,540 runs.

  • Line execution difference (0.000015) milliseconds.
  • Avg difference (3.365) milliseconds per 217,377 loops.
  • Total difference 67.30 milliseconds for 4,347,540 loops

The iteration variablity for Code 1 was (1.3122) milliseconds and Code 2 was (4.5683) 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']);
