The test labeled "require" was the faster by 0.0519 seconds, (4.853% faster)

require 100%
file_exists() 95.147%

The require test took 1.0177 seconds.
The file_exists() test took 1.0696 seconds.


Each test case ran 20 random code order iterations consisting of 285,472 loops for a total of 5,709,440 runs.

  • Line execution difference (0.000009) milliseconds.
  • Avg difference (2.595) milliseconds per 285,472 loops.
  • Total difference 51.91 milliseconds for 5,709,440 loops

The iteration variablity for Code 1 was (6.4634) milliseconds and Code 2 was (1.4892) 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:
