PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: (array) vs. array

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

Result: Discarded

The test labeled "(array)" was the faster by 0.0967 seconds, (5.543% faster)

(array) 100%
array() 94.457%

The (array) test took 1.6474 seconds.
The array() test took 1.7441 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 287,773 loops for a total of 5,755,460 runs.

  • Line execution difference (0.000017) milliseconds.
  • Avg difference (4.834) milliseconds per 287,773 loops.
  • Total difference 96.67 milliseconds for 5,755,460 loops

The iteration variablity for Code 1 was (14.7926) milliseconds and Code 2 was (16.9328) 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);
