No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "else if" was the faster by 0.0238 seconds, (2.424% faster)

else if 100%
elseif 97.576%

The else if test took 0.9581 seconds.
The elseif test took 0.9819 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 266,601 loops for a total of 5,332,020 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.190) milliseconds per 266,601 loops.
  • Total difference 23.80 milliseconds for 5,332,020 loops

The iteration variablity for Code 1 was (0.4652) milliseconds and Code 2 was (0.8602) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "else if", was:

if ($GLOBALS['dummy_false'])
	$GLOBALS['dummy_false'] = true;
else if ($GLOBALS['dummy_true'])
	$GLOBALS['dummy_true'] = true;

The second test, "elseif", was:

if ($GLOBALS['dummy_false'])
	$GLOBALS['dummy_false'] = true;
elseif ($GLOBALS['dummy_true'])
	$GLOBALS['dummy_true'] = true;
