Historical Results

Based on (1) saved test runs, The test labeled "(array)" was (on average) the faster by 0.0102 seconds, (1.045% faster)

(array) 100%
array() 98.955%

The (array) test took 0.9653 seconds.
The array() test took 0.9754 seconds.


Each test case ran 20 random code order iterations consisting of 224,835 loops for a total of 4,496,700 runs.

  • Line execution difference (0.000002) milliseconds.
  • Avg difference (0.000) milliseconds per 224,835 loops.
  • Total difference 10.19 milliseconds for 4,496,700 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);
