Result: Discarded

The test labeled "file()" was the faster by 0.0252 seconds, (2.311% faster)

file() 100%
fgets() 97.689%

The file() test took 1.0666 seconds.
The fgets() test took 1.0919 seconds.


Each test case ran 20 random code order iterations consisting of 275,126 loops for a total of 5,502,520 runs.

  • Line execution difference (0.000005) milliseconds.
  • Avg difference (1.262) milliseconds per 275,126 loops.
  • Total difference 25.23 milliseconds for 5,502,520 loops

The iteration variablity for Code 1 was (1.6009) milliseconds and Code 2 was (2.6054) 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));
