Historical Results

Based on (1) saved test runs, The test labeled "file_exists()" was (on average) the faster by 0.0286 seconds, (5.410% faster)

file_exists() 100%
require 94.59%

The file_exists() test took 0.4995 seconds.
The require test took 0.5281 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 132,699 loops for a total of 2,653,980 runs.

  • Line execution difference (0.000011) milliseconds.
  • Avg difference (0.000) milliseconds per 132,699 loops.
  • Total difference 28.57 milliseconds for 2,653,980 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "file_exists()", was:

clearstatcache();

if (!file_exists('supplement/dummy.inc'))
	trigger_error('Required file not found!', E_USER_ERROR);
include('supplement/dummy.inc');

The second test, "require", was:

clearstatcache();
require('supplement/dummy.inc');
