Result: Discarded

The test labeled "list ($v) =" was the faster by 0.0307 seconds, (4.276% faster)

list ($v) = 100%
$array[0] 95.724%

The list ($v) = test took 0.6881 seconds.
The $array[0] test took 0.7188 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 165,635 loops for a total of 3,312,700 runs.

  • Line execution difference (0.000009) milliseconds.
  • Avg difference (1.537) milliseconds per 165,635 loops.
  • Total difference 30.74 milliseconds for 3,312,700 loops

The iteration variablity for Code 1 was (2.1617) milliseconds and Code 2 was (2.6031) milliseconds. The lower and the closer together there values are the more accurate the results are.

Code

The first test, "list ($v) =", was:

list ($v) = $GLOBALS['array'];

The second test, "$array[0]", was:

$v = $GLOBALS['array'][0];
