Historical Results

Based on (1) saved test runs, The test labeled "elseif" was (on average) the faster by 0.0492 seconds, (6.371% faster)

elseif 100%
else if 93.629%

The elseif test took 0.7237 seconds.
The else if test took 0.7729 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 140,760 loops for a total of 2,815,200 runs.

  • Line execution difference (0.000017) milliseconds.
  • Avg difference (0.000) milliseconds per 140,760 loops.
  • Total difference 49.24 milliseconds for 2,815,200 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.

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;
