The test labeled "(array)" was the faster by 0.0164 seconds, (1.666% faster)

(array) 100%

is_array() ? x : array(x) 98.334%

The (array) test took 0.9707 seconds.
The is_array() ? x : array(x) test took 0.9871 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 257,516 loops for a total of 5,150,320 runs.

Line execution difference (0.000003) milliseconds.
Avg difference (0.822) milliseconds per 257,516 loops.
Total difference 16.44 milliseconds for 5,150,320 loops

The iteration variablity for Code 1 was (3.6473) milliseconds and Code 2 was (3.5236) 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);
