Result: Discarded

The test labeled "file_get_contents()" was the faster by 0.0125 seconds, (1.365% faster)

file_get_contents() 100%
file() 98.635%

The file_get_contents() test took 0.904 seconds.
The file() test took 0.9165 seconds.


Each test case ran 20 random code order iterations consisting of 231,697 loops for a total of 4,633,940 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.626) milliseconds per 231,697 loops.
  • Total difference 12.51 milliseconds for 4,633,940 loops

The iteration variablity for Code 1 was (5.2477) milliseconds and Code 2 was (4.5613) 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;
