PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: (array) vs. array

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

Run this test again Return to test menu

Result: Discarded

The test labeled "(array)" was the faster by 0.0218 seconds, (4.453% faster)

(array) 100%
array() 95.547%

The (array) test took 0.4669 seconds.
The array() test took 0.4887 seconds.


Each test case ran 20 random code order iterations consisting of 130,268 loops for a total of 2,605,360 runs.

  • Line execution difference (0.000008) milliseconds.
  • Avg difference (1.088) milliseconds per 130,268 loops.
  • Total difference 21.76 milliseconds for 2,605,360 loops

The iteration variablity for Code 1 was (0.8562) milliseconds and Code 2 was (1.5076) 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);
