PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: (array) vs. array w/is_array

Does the (array) cast work better than the array() construct if you might already have an array?

Result: Discarded

The test labeled "(array)" was the faster by 0.0198 seconds, (3.243% faster)

(array) 100%
is_array() ? x : array(x) 96.757%

The (array) test took 0.5919 seconds.
The is_array() ? x : array(x) test took 0.6117 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 141,675 loops for a total of 2,833,500 runs.

  • Line execution difference (0.000007) milliseconds.
  • Avg difference (0.992) milliseconds per 141,675 loops.
  • Total difference 19.84 milliseconds for 2,833,500 loops

The iteration variablity for Code 1 was (5.3499) milliseconds and Code 2 was (6.1610) 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);
