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 0.005 seconds, (0.480% faster)

array() 100%
(array) 99.52%

The array() test took 1.0416 seconds.
The (array) test took 1.0466 seconds.


Each test case ran 20 random code order iterations consisting of 279,247 loops for a total of 5,584,940 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.251) milliseconds per 279,247 loops.
  • Total difference 5.02 milliseconds for 5,584,940 loops

The iteration variablity for Code 1 was (3.8461) milliseconds and Code 2 was (3.3467) milliseconds. The lower and the closer together there values are the more accurate the results are.


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);
