AP\Conf is a library for managing project configuration variables, featuring validation and object transformation capabilities.

Features

• Retrieve environment variables and PHP configuration files as objects with validation.
• Built-in validation mechanisms with error handling.

Requirements

• PHP 8.3 or higher

Getting started

Lazy Loading with MyConf

You can create a custom configuration loader using a static class that extends Conf

use AP\Conf\Conf;
use AP\Scheme\ToObject;
use AP\Scheme\Validation;

readonly class SecuritySettings implements ToObject, Validation {
    public function __construct() {
        public string $salt
    }
}

class MyConf extends Conf
{
    public static function security(): SecuritySettings
    {
        return self::obj(__FUNCTION__, SecuritySettings::class);
    }
}

class Core 
{
    static public function conf(): MyConf
    {
        return new MyConf(
            [
                __DIR__ . "/../conf",
                __DIR__ . "/../conf/local",
            ]
        );
    }
}

$salt = Core::conf()->security()->salt;

Configuration Loading Behavior

1. The library first checks the $_SERVER['security'] variable first, expecting a JSON string.
2. If not found in the environment variables, it merges values from the following files if they exist:
   • __DIR__/../conf/security.php
   • __DIR__/../conf/local/security.php
3. Values from the next file, such as conf/local/security.php, take priority and override those from the previous file, such as conf/security.php.
