README

Benchmark

Provides the ability to do simple performance tests on code blocks.

Installation

Install with Composer:

composer require tankfairies/benchmark 

Usage

Server Details

This will output an array of basic details on the machine you're running performance testing on.

For server details: -

$server = new Server();
$details = $server->getDetails();

Output Example: -

Array (
    [PHP] => 8.2.16
    [Platform] => Darwin
    [Arch] => arm64
    [Max memory usage] => 128M
    [OPCache status] => disabled
    [OPCache JIT] => disabled/unavailable
    [PCRE JIT] => enabled
    [XDebug extension] => disabled
)

For installed extensions: -

$server = new Server();
$extensions = $server->getInstalledExtensions();

Output Example: -

Array
(
    [0] => Core
    [1] => date
    [2] => libxml
    [3] => openssl
    [4] => pcre
    [5] => sqlite3
    [6] => zlib
    [7] => bcmath
    ...

Stopwatch

Handles the time recording for benchmarking.

Benchmark

Call or place the code you want to test into an anonymous function, for example: -

$func = function () {
    rand(1, 100000);
};

Setup the benchmark as below: -

$benchmark = new Benchmark(new Stopwatch());
$completion = $benchmark
    ->multiplier(200000, 5)
    ->script($func)
    ->run();

You can define your own run criteria for example the above will run the test 200000 times for a total of 5 loops. This will produce 5 sets of results in seconds in the format: -

Array (
    [1] => 0.1699
    [2] => 0.1642
    [3] => 0.1641
    [4] => 0.1643
    [5] => 0.1645
)

The above shows the execution time in seconds for each 200k run.
