Result: Discarded

The test labeled "file()" was the faster by 0.0321 seconds, (6.211% faster)

file() 100%
fgets() 93.789%

The file() test took 0.485 seconds.
The fgets() test took 0.5171 seconds.


Each test case ran 20 random code order iterations consisting of 130,714 loops for a total of 2,614,280 runs.

  • Line execution difference (0.000012) milliseconds.
  • Avg difference (1.606) milliseconds per 130,714 loops.
  • Total difference 32.12 milliseconds for 2,614,280 loops

The iteration variablity for Code 1 was (2.0208) milliseconds and Code 2 was (4.2176) 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));
