Historical Results

Based on (1) saved test runs, The test labeled "fgets()" was (on average) the faster by 0.0174 seconds, (1.660% faster)

fgets() 100%
file() 98.34%

The fgets() test took 1.03 seconds.
The file() test took 1.0474 seconds.


Each test case ran 20 random code order iterations consisting of 283,878 loops for a total of 5,677,560 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 283,878 loops.
  • Total difference 17.38 milliseconds for 5,677,560 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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));
