The test labeled "require" was the faster by 0.0973 seconds, (9.072% faster)

require 100%
file_exists() 90.928%

The require test took 0.9748 seconds.
The file_exists() test took 1.072 seconds.


Each test case ran 20 random code order iterations consisting of 258,787 loops for a total of 5,175,740 runs.

  • Line execution difference (0.000019) milliseconds.
  • Avg difference (4.863) milliseconds per 258,787 loops.
  • Total difference 97.26 milliseconds for 5,175,740 loops

The iteration variablity for Code 1 was (8.0087) milliseconds and Code 2 was (3.5137) 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:
