README

Simple library to get environment variables converted to simple types.

Installation

This package is installable and autoloadable via Composer as oscarotero/env.

$ composer require deinternetjongens/env

Example

// Using getenv function:
var_dump(getenv('FOO')); //string(5) "false"

// Using Env:
var_dump(Env::get('FOO')); //bool(false)

Available conversions:

• "false" is converted to boolean false
• "true" is converted to boolean true
• "null" is converted to null
• If the string contains only numbers is converted to an integer
• If the string has quotes, remove them

To configure the conversion, you can use the following constants (all enabled by default):

• Env::CONVERT_BOOL To convert boolean values
• Env::CONVERT_NULL To convert null values
• Env::CONVERT_INT To convert integer values
• Env::STRIP_QUOTES To remove the quotes of the strings

//Convert booleans and null, but not integers or strip quotes
Env::$options = Env::CONVERT_BOOL | Env::CONVERT_NULL;

Default value

By default, if the value does not exits, returns null, but you can change for any other value:

Env::$default = false;

The env() function

If you don't want to complicate with classes and namespaces, you can use the env() function, like in Laravel or other libraries:

Env::init(); //expose the function to globals

//now you can use it

var_dump(env('FOO'));
