The test labeled "file_exists()" was the faster by 0.0363 seconds, (6.073% faster)

file_exists() 100%
require 93.927%

The file_exists() test took 0.5608 seconds.
The require test took 0.597 seconds.


Each test case ran 20 random code order iterations consisting of 135,420 loops for a total of 2,708,400 runs.

  • Line execution difference (0.000013) milliseconds.
  • Avg difference (1.813) milliseconds per 135,420 loops.
  • Total difference 36.26 milliseconds for 2,708,400 loops

The iteration variablity for Code 1 was (3.7512) milliseconds and Code 2 was (4.4344) milliseconds. The lower and the closer together there values are the more accurate the results are.


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


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

The second test, "require", was:
