Historical Results

Based on (3) saved test runs, The test labeled "$array[0]" was (on average) the faster by 0.0056 seconds, (0.579% faster)

$array[0] 100%
list ($v) = 99.421%

The $array[0] test took 0.9544 seconds.
The list ($v) = test took 0.96 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 232,118 loops for a total of 4,642,367 runs.

  • Line execution difference (0.000001) milliseconds.
  • Avg difference (0.000) milliseconds per 232,118 loops.
  • Total difference 5.55 milliseconds for 4,642,367 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.

Code

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

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

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

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