No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "sprintf()" was the faster by 0.0601 seconds, (4.257% faster)

sprintf() 100%
commas 95.743%

The sprintf() test took 1.3518 seconds.
The commas test took 1.4119 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 273,022 loops for a total of 5,460,440 runs.

  • Line execution difference (0.000011) milliseconds.
  • Avg difference (3.005) milliseconds per 273,022 loops.
  • Total difference 60.11 milliseconds for 5,460,440 loops

The iteration variablity for Code 1 was (15.3270) milliseconds and Code 2 was (16.6138) 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']);
