Result: Discarded
The test labeled "min()/max()" was the faster by 0.0197 seconds, (1.833% faster)
The min()/max() test took 1.0548 seconds.
The ifs test took 1.0745 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 284,600 loops for a total of 5,692,000 runs.
- Line execution difference (0.000003) milliseconds.
- Avg difference (0.985) milliseconds per 284,600 loops.
- Total difference 19.69 milliseconds for 5,692,000 loops
The iteration variablity for Code 1 was (2.4647) milliseconds and Code 2 was (2.2266) milliseconds. The lower and the closer together there values are the more accurate the results are.
Code
The first test, "min()/max()", was:
$GLOBALS['dummy'] = 83; for ($j = 0; $j < 100; $j++) $GLOBALS['dummy2'] = min(50, max(20, $GLOBALS['dummy']));
The second test, "ifs", was:
$GLOBALS['dummy'] = 83;
for ($j = 0; $j < 100; $j++)
{
if ($GLOBALS['dummy'] < 20)
$GLOBALS['dummy2'] = 20;
elseif ($GLOBALS['dummy'] > 50)
$GLOBALS['dummy2'] = 50;
else
$GLOBALS['dummy2'] = $GLOBALS['dummy'];
