PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: (array) vs. array

Does the (array) cast work better than the array() construct?

Result: Saved

The test labeled "(array)" was the faster by 0.0065 seconds, (0.762% faster)

(array) 100%
array() 99.238%

The (array) test took 0.8473 seconds.
The array() test took 0.8538 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 215,534 loops for a total of 4,310,680 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.325) milliseconds per 215,534 loops.
  • Total difference 6.51 milliseconds for 4,310,680 loops

The iteration variablity for Code 1 was (2.1416) milliseconds and Code 2 was (2.1521) 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, "array()", was:

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