Support us
----------

[](#support-us)

Roots is an independent open source org, supported only by developers like you. Your sponsorship funds [WP Packages](https://wp-packages.org/) and the entire Roots ecosystem, and keeps them independent. Support us by purchasing [Radicle](https://roots.io/radicle/) or [sponsoring us on GitHub](https://github.com/sponsors/roots) — sponsors get access to our private Discord.

Requirements
------------

[](#requirements)

- PHP 5.6+

Installation
------------

[](#installation)

```
composer require roots/support
```

Helpers
-------

[](#helpers)

This package autoloads `helpers.php` and provides:

- `Roots\env($key, $default = null)`
    Laravel-compatible environment lookup.
    Deprecated when `\Illuminate\Support\Env` is available (it delegates there automatically).
- `Roots\value($value)`
    Returns `$value()` if the value is a closure, otherwise returns the value unchanged.
- `Roots\add_filters(iterable $filters, $callback, $priority = 10, $args = 2)`
    Registers one callback across many filter hooks.
- `Roots\remove_filters(iterable $filters, $callback, $priority = 10)`
    Removes one callback across many filter hooks.
- `Roots\add_actions(iterable $actions, $callback, $priority = 10, $args = 2)`
    Alias of `add_filters`.
- `Roots\remove_actions(iterable $actions, $callback, $priority = 10)`
    Alias of `remove_filters`.
- `Roots\wp_die($message, $subtitle = '', $title = '', $footer = '')`
    Wrapper around WordPress `wp_die()` with Roots-flavored defaults.
