The test labeled "list ($v) =" was the faster by 0.0348 seconds, (3.374% faster)

list ($v) = 100%
$array[0] 96.626%

The list ($v) = test took 0.9964 seconds.
The $array[0] test took 1.0312 seconds.


Each test case ran 20 random code order iterations consisting of 281,213 loops for a total of 5,624,260 runs.

  • Line execution difference (0.000006) milliseconds.
  • Avg difference (1.740) milliseconds per 281,213 loops.
  • Total difference 34.79 milliseconds for 5,624,260 loops

The iteration variablity for Code 1 was (0.5960) milliseconds and Code 2 was (1.8914) milliseconds. The lower and the closer together there values are the more accurate the results are.


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

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

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

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