PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: @ (no error)

No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "without @" was the faster by 0.0419 seconds, (3.526% faster)

without @ 100%
@ (shut up) 96.474%

The without @ test took 1.1473 seconds.
The @ (shut up) test took 1.1893 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 287,971 loops for a total of 5,759,420 runs.

  • Line execution difference (0.000007) milliseconds.
  • Avg difference (2.097) milliseconds per 287,971 loops.
  • Total difference 41.94 milliseconds for 5,759,420 loops

The iteration variablity for Code 1 was (10.0472) milliseconds and Code 2 was (5.6834) 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']++;
