Historical Results

Based on (4) saved test runs, The test labeled "(array)" was (on average) the faster by 0.0093 seconds, (1.376% faster)

(array) 100%
array() 98.624%

The (array) test took 0.6672 seconds.
The array() test took 0.6765 seconds.


Each test case ran 20 random code order iterations consisting of 177,445 loops for a total of 3,548,905 runs.

  • Line execution difference (0.000003) milliseconds.
  • Avg difference (0.000) milliseconds per 177,445 loops.
  • Total difference 9.31 milliseconds for 3,548,905 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);
