No Description

Run this test again Return to test menu

Result: Discarded

The test labeled "elseif" was the faster by 0.0161 seconds, (2.634% faster)

elseif 100%
else if 97.366%

The elseif test took 0.5964 seconds.
The else if test took 0.6125 seconds.


Each test case ran 20 random code order iterations consisting of 134,164 loops for a total of 2,683,280 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (0.807) milliseconds per 134,164 loops.
  • Total difference 16.14 milliseconds for 2,683,280 loops

The iteration variablity for Code 1 was (4.6828) milliseconds and Code 2 was (4.5170) 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;
