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 0.0291 seconds, (4.388% faster)

(array) 100%
array() 95.612%

The (array) test took 0.6342 seconds.
The array() test took 0.6633 seconds.


Each test case ran 20 random code order iterations consisting of 151,871 loops for a total of 3,037,420 runs.

  • Line execution difference (0.000010) milliseconds.
  • Avg difference (1.455) milliseconds per 151,871 loops.
  • Total difference 29.11 milliseconds for 3,037,420 loops

The iteration variablity for Code 1 was (1.9146) milliseconds and Code 2 was (3.6289) 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);
