Historical Results

Based on (4) saved test runs, The test labeled "require" was (on average) the faster by 0.0086 seconds, (1.158% faster)

require 100%
file_exists() 98.842%

The require test took 0.737 seconds.
The file_exists() test took 0.7456 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 156,486 loops for a total of 3,129,710 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 156,486 loops.
  • Total difference 8.63 milliseconds for 3,129,710 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');
