Historical Results

Based on (2) saved test runs, The test labeled "array()" was (on average) the faster by 0.002 seconds, (0.360% faster)

array() 100%
(array) 99.64%

The array() test took 0.548 seconds.
The (array) test took 0.55 seconds.


Each test case ran 20 random code order iterations consisting of 131,889 loops for a total of 2,637,780 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 131,889 loops.
  • Total difference 1.98 milliseconds for 2,637,780 loops

The iteration variablity for Code 1 was (0.0000) milliseconds and Code 2 was (0.0000) 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);
