Result: Discarded

The test labeled "file()" was the faster by 0.0224 seconds, (2.375% faster)

file() 100%
file_get_contents() 97.625%

The file() test took 0.9227 seconds.
The file_get_contents() test took 0.9451 seconds.


Each test case ran 20 random code order iterations consisting of 245,748 loops for a total of 4,914,960 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.122) milliseconds per 245,748 loops.
  • Total difference 22.44 milliseconds for 4,914,960 loops

The iteration variablity for Code 1 was (2.1380) milliseconds and Code 2 was (1.2511) milliseconds. The lower and the closer together there values are the more accurate the results are.


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

$lines = file('supplement/');
foreach ($lines as $line)
	$GLOBALS['dummy2'] = rtrim($line);

The second test, "file_get_contents()", was:

$lines = explode("\n", str_replace(array("\r\n", "\r"), "\n", file_get_contents('supplement/')));
foreach ($lines as $line)
	$GLOBALS['dummy2'] = $line;
