Result: Discarded

The test labeled "file()" was the faster by 0.0918 seconds, (12.699% faster)

file() 100%
file_get_contents() 87.301%

The file() test took 0.6308 seconds.
The file_get_contents() test took 0.7226 seconds.


Each test case ran 20 random code order iterations consisting of 147,453 loops for a total of 2,949,060 runs.

  • Line execution difference (0.000031) milliseconds.
  • Avg difference (4.588) milliseconds per 147,453 loops.
  • Total difference 91.76 milliseconds for 2,949,060 loops

The iteration variablity for Code 1 was (5.9662) milliseconds and Code 2 was (8.7394) 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;
