Result: Discarded

The test labeled "is_array() ? x : array(x)" was the faster by 0.0124 seconds, (1.692% faster)

is_array() ? x : array(x) 100%

(array) 98.308%

The is_array() ? x : array(x) test took 0.7208 seconds.
The (array) test took 0.7332 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 183,117 loops for a total of 3,662,340 runs.

Line execution difference (0.000003) milliseconds.
Avg difference (0.620) milliseconds per 183,117 loops.
Total difference 12.41 milliseconds for 3,662,340 loops

The iteration variablity for Code 1 was (5.3153) milliseconds and Code 2 was (3.6928) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "(array)", was:

for ($j = 0; $j < 1000; $j++)
	$GLOBALS['dummy'] = (array) $j;

The second test, "is_array() ? x : array(x)", was:

for ($j = 0; $j < 1000; $j++)
	$GLOBALS['dummy'] = is_array($j) ? $j : array($j);
