The test labeled "(array)" was the faster by 0.0183 seconds, (1.825% faster)

(array) 100%

is_array() ? x : array(x) 98.175%

The (array) test took 0.9863 seconds.
The is_array() ? x : array(x) test took 1.0046 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 275,171 loops for a total of 5,503,420 runs.

Line execution difference (0.000003) milliseconds.
Avg difference (0.917) milliseconds per 275,171 loops.
Total difference 18.33 milliseconds for 5,503,420 loops

The iteration variablity for Code 1 was (1.4318) milliseconds and Code 2 was (1.4628) 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);
