Result: Discarded

The test labeled "$array[0]" was the faster by 0.0209 seconds, (1.893% faster)

$array[0] 100%
list ($v) = 98.107%

The $array[0] test took 1.0815 seconds.
The list ($v) = test took 1.1024 seconds.


Each test case ran 20 random code order iterations consisting of 283,734 loops for a total of 5,674,680 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (1.044) milliseconds per 283,734 loops.
  • Total difference 20.87 milliseconds for 5,674,680 loops

The iteration variablity for Code 1 was (5.4245) milliseconds and Code 2 was (3.3339) 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];
