Historical Results

Based on (4) saved test runs, The test labeled "list ($v) =" was (on average) the faster by 0.0003 seconds, (0.057% faster)

list ($v) = 100%
$array[0] 99.943%

The list ($v) = test took 0.5198 seconds.
The $array[0] test took 0.5201 seconds.


Each test case ran 20 random code order iterations consisting of 139,441 loops for a total of 2,788,810 runs.

  • Line execution difference (0.000000) milliseconds.
  • Avg difference (0.000) milliseconds per 139,441 loops.
  • Total difference 0.30 milliseconds for 2,788,810 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, "list ($v) =", was:

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

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

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