The test labeled "fgets()" was the faster by 0.0011 seconds, (0.203% faster)

fgets() 100%
file() 99.797%

The fgets() test took 0.5294 seconds.
The file() test took 0.5305 seconds.


Each test case ran 20 random code order iterations consisting of 138,540 loops for a total of 2,770,800 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.054) milliseconds per 138,540 loops.
  • Total difference 1.08 milliseconds for 2,770,800 loops

The iteration variablity for Code 1 was (1.9042) milliseconds and Code 2 was (1.9066) 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, "fgets()", was:

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