Test: (int) vs. settype
If you already have a variable, logic tells us that changing is type might be faster than creating a new value (which a cast does.) But, is this true?

Based on (3) saved test runs, The test labeled "(int)" was (on average) the faster by 0.0229 seconds, (2.020% faster)
The (int) test took 1.1096 seconds.
The settype() test took 1.1325 seconds.
Nitty-Gritty
Each test case ran 20 random code order iterations consisting of 284,107 loops for a total of 5,682,147 runs.
- Line execution difference (0.000004) milliseconds.
- Avg difference (0.000) milliseconds per 284,107 loops.
- Total difference 22.88 milliseconds for 5,682,147 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, "(int)", was:
for ($j = 0; $j < 100; $j++)
{
$i = '42 ';
$i = (int) $i;
}
The second test, "settype()", was:
for ($j = 0; $j < 100; $j++)
{
$i = '42 ';
settype($i, 'int');
}
