PHP Benchmarks

Performance comparison of PHP code alternatives.

Test: list vs. [0]

These tests use an array with many values in it.

Result: Discarded

The test labeled "$array[0]" was the faster by 0.0097 seconds, (1.774% faster)

$array[0] 100%
list ($v) = 98.226%

The $array[0] test took 0.5343 seconds.
The list ($v) = test took 0.544 seconds.

Nitty-Gritty

Each test case ran 20 random code order iterations consisting of 136,611 loops for a total of 2,732,220 runs.

  • Line execution difference (0.000004) milliseconds.
  • Avg difference (0.483) milliseconds per 136,611 loops.
  • Total difference 9.65 milliseconds for 2,732,220 loops

The iteration variablity for Code 1 was (1.7853) milliseconds and Code 2 was (1.2793) 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];
