Result: Discarded

The test labeled "fgets()" was the faster by 0.0982 seconds, (7.485% faster)

fgets() 100%
file() 92.515%

The fgets() test took 1.2134 seconds.
The file() test took 1.3116 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 284,311 loops for a total of 5,686,220 runs.

  • Line execution difference (0.000017) milliseconds.
  • Avg difference (4.908) milliseconds per 284,311 loops.
  • Total difference 98.17 milliseconds for 5,686,220 loops

The iteration variablity for Code 1 was (11.7092) milliseconds and Code 2 was (7.6528) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "file()", was:

$lines = file('supplement/dummy.inc');
foreach ($lines as $line)
	$GLOBALS['dummy2'] = rtrim($line);

The second test, "fgets()", was:

$fp = fopen('supplement/dummy.inc', 'rt');
while (!feof($fp))
	$GLOBALS['dummy2'] = rtrim(fgets($fp));
fclose($fp);
