Test: @ (no error)

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "@ (shut up)" was the faster by 0.0886 seconds, (14.252% faster)

@ (shut up) 100%
without @ 85.748%

The @ (shut up) test took 0.5329 seconds.
The without @ test took 0.6215 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 143,911 loops for a total of 2,878,220 runs.

  • Line execution difference (0.000031) milliseconds.
  • Avg difference (4.429) milliseconds per 143,911 loops.
  • Total difference 88.58 milliseconds for 2,878,220 loops

The iteration variablity for Code 1 was (0.9604) milliseconds and Code 2 was (3.6852) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "@ (shut up)", was:

@$GLOBALS['dummy']++;

The second test, "without @", was:

$GLOBALS['dummy']++;
