PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: list vs. [0]

These tests use an array with many values in it.

Run this test again Return to test menu

Result: Discarded

The test labeled "$array[0]" was the faster by 0.0102 seconds, (1.945% faster)

$array[0] 100%
list ($v) = 98.055%

The $array[0] test took 0.5142 seconds.
The list ($v) = test took 0.5244 seconds.


Each test case ran 20 random code order iterations consisting of 129,055 loops for a total of 2,581,100 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.510) milliseconds per 129,055 loops.
  • Total difference 10.20 milliseconds for 2,581,100 loops

The iteration variablity for Code 1 was (5.0531) milliseconds and Code 2 was (4.8990) 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];
