Historical Results

Based on (3) saved test runs, The test labeled "(array)" was (on average) the faster by 0.0129 seconds, (1.721% faster)

(array) 100%
array() 98.279%

The (array) test took 0.7339 seconds.
The array() test took 0.7467 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 189,634 loops for a total of 3,792,680 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 189,634 loops.
  • Total difference 12.85 milliseconds for 3,792,680 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.

Code

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);
