file() 100%
file_get_contents() 99.484%

The file() test took 0.9636 seconds.
The file_get_contents() test took 0.9686 seconds.


Each test case ran 20 random code order iterations consisting of 257,667 loops for a total of 5,153,348 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 257,667 loops.
  • Total difference 5.00 milliseconds for 5,153,348 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.


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;
