README

Utils to load, parse and work with configuration on Mezzio projects.

This library is based on the shlinkio/shlink-config project, with some modifications and extensions for our specific requirements.

Installation

composer install sirix/sirix-config

This library is also a mezzio module which provides its own ConfigProvider. Add it to your configuration to get everything automatically set up.

Included utils

Global functions

All functions are available globally (no use function needed):

• env(string $key, mixed $default = null, ?string $type = null): mixed — Read an environment variable with optional type casting.
• parseEnvVar(string $value): string|int|bool|null — Parse a raw env value (handles true, false, null, empty, numeric).
• castEnvValue(string $value, string $type): mixed — Cast a raw env string to the specified type.
• formatEnvVarValue(mixed $value): string — Format a value for use as an env var string.
• formatEnvVarValueOrNull(mixed $value): string|null — Same as above, returns null for non-scalar/non-array values.
• loadConfigFromGlob(string $globPattern): array — Load and merge all PHP config files matching a glob pattern.
• loadEnvVarsFromConfig(string $configPath, ?array $allowedEnvVars = null): void — Load config and set env vars from it.
• putNotYetDefinedEnv(string $key, mixed $value): void — Set an env var only if it is not already defined.

env() function

// Without type (auto-detect: bool, int, string, null)
env('DEBUG');              // true
env('PORT');               // 8080
env('NAME', 'default');    // 'default' if NAME is not set

// With explicit type casting
env('PORT', '8080', 'int');       // (int) 8080
env('RATE', '3.14', 'float');     // (float) 3.14
env('NAME', 'foo', 'string');     // 'foo'
env('DEBUG', 'true', 'bool');     // true
env('HOSTS', 'a,b,c', 'array');   // ['a', 'b', 'c']

Supported types: int/integer, float/double, string, bool/boolean, array (comma-separated).

Config providers and factories

• EnvVarLoaderProvider: A config provider which loads the entries of the loaded config into env vars and always returns empty. Designed to be the first config provider in the pipeline.

• DottedAccessConfigAbstractFactory: An abstract factory that lets any config param to be fetched as a service by using the config.foo.bar notation.

• ValinorConfigFactory: A PSR-11 factory that lets you map arbitrary objects from arrays, using cuyz/valinor.

  In order to use it, you have to register the object to map as a service, and the ValinorConfigFactory with static access using the service that returns the raw array with the data as the static method name:

  <?php
  
  declare(strict_types=1);
  
  return [
      MyCoolOptions::class => [ValinorConfigFactory::class, 'config.foo.options'],
  ];

  It is useful to combine this factory with the DottedAccessConfigAbstractFactory.

Valinor cache configuration

ValinorConfigFactory supports an optional filesystem cache, configurable under the sirix_config.valinor key in your application config. Options:

• cache (bool): Enable/disable Valinor mapping cache. Default: false.
• cache_directory (string): Directory where cache files are stored. Default: data/cache/valinor.
• development_mode (bool): When true, enables file-watching cache to auto‑invalidate entries when source files change. Default: false.

Example config:

<?php

declare(strict_types=1);

return [
    'sirix_config' => [
        'valinor' => [
            'cache' => true,
            'cache_directory' => 'data/cache/valinor',
            'development_mode' => true,
        ],
    ],
];
