Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 272,445 loops for a total of 5,448,900 runs.

Line execution difference (0.000012) milliseconds.
Avg difference (3.258) milliseconds per 272,445 loops.
Total difference 65.16 milliseconds for 5,448,900 loops

The iteration variablity for Code 1 was (8.3088) milliseconds and Code 2 was (5.8478) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "is_float", was:

$a = is_float($GLOBALS['test']);

The second test, "Casting", was:

$a = (float) $GLOBALS['test'] === $GLOBALS['test'];
