Based on (3) saved test runs, The test labeled "file()" was (on average) the faster by 0.0223 seconds, (2.683% faster)

file() 100%
file_get_contents() 97.317%

The file() test took 0.8078 seconds.
The file_get_contents() test took 0.8301 seconds.


Each test case ran 20 random code order iterations consisting of 220,286 loops for a total of 4,405,727 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (0.000) milliseconds per 220,286 loops.
  • Total difference 22.27 milliseconds for 4,405,727 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;
