EnvReader

PHP Environment Reader

Simple Environment Reader which can parse the Value to a specific type. It tries to find the Value in $_ENV, $_SERVER and via getenv. The logic is leaned on the EnvVarProcessor from Symfony.

Installation

composer require devcirclede/env-reader

Supported Types

Actual included Types are:

• integer
• float
• string
• boolean
• array
• json

You can add your own Type by creating a class which implements the TypeInterface.

Example:

<?php

declare(strict_types=1);

namespace Company\EnvTypes;

use DevCircleDe\EnvReader\Types\TypeInterface;

class CustomType implements TypeInterface
{
    public function getName(): string
    {
        return 'custom';
    }
    
    public function convert(string $value): mixed
    {
        // convert the value to custom type
        return $value;
    }
}

Usage of the CustomType:

<?php

use Company\EnvTypes\CustomType;
use DevCircleDe\EnvReader\EnvParser;

$envParser = EnvParser::getInstance();
// add custom type
$envParser->getCollection()->addItem(new CustomType());

// read Env
$var = $envParser->parse('FOO', 'custom_type');
