Result: Saved

The test labeled "file()" was the faster by 0.02 seconds, (1.990% faster)

file() 100%
fgets() 98.01%

The file() test took 0.9868 seconds.
The fgets() test took 1.0068 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 274,227 loops for a total of 5,484,540 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.002) milliseconds per 274,227 loops.
  • Total difference 20.04 milliseconds for 5,484,540 loops

The iteration variablity for Code 1 was (0.5794) milliseconds and Code 2 was (0.6193) 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);
