Result: Discarded

The test labeled "file()" was the faster by 0.0532 seconds, (5.014% faster)

file() 100%
file_get_contents() 94.986%

The file() test took 1.0075 seconds.
The file_get_contents() test took 1.0607 seconds.


Each test case ran 20 random code order iterations consisting of 284,359 loops for a total of 5,687,180 runs.

  • Line execution difference (0.000009) milliseconds.
  • Avg difference (2.659) milliseconds per 284,359 loops.
  • Total difference 53.19 milliseconds for 5,687,180 loops

The iteration variablity for Code 1 was (1.3167) milliseconds and Code 2 was (4.6384) 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;
