No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "elseif" was the faster by 0.0104 seconds, (1.981% faster)

elseif 100%
else if 98.019%

The elseif test took 0.5153 seconds.
The else if test took 0.5257 seconds.


Each test case ran 20 random code order iterations consisting of 122,595 loops for a total of 2,451,900 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.521) milliseconds per 122,595 loops.
  • Total difference 10.41 milliseconds for 2,451,900 loops

The iteration variablity for Code 1 was (4.7787) milliseconds and Code 2 was (3.9428) milliseconds. The lower and the closer together there values are the more accurate the results are.


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;
