README

redot/dotenv-editor is a PHP package that provides a simple and convenient way to read, modify, and save environment variables from a .env file. It utilizes the Dotenv package for parsing the environment file.

Installation

You can install the package via Composer:

composer require redot/dotenv-editor

Usage

Creating an Instance

To use the DotenvEditor class, create an instance by providing the path to the .env file:

use Redot\DotenvEditor\DotenvEditor;

$editor = new DotenvEditor('/path/to/.env');

Optionally, you can pass a second parameter to enable backup functionality:

$editor = new DotenvEditor('/path/to/.env', true);

Getting Environment Variables

You can retrieve the value of an environment variable by specifying its key:

$value = $editor->get('KEY');

If the key is not found, you can provide a default value that will be returned instead:

$value = $editor->get('KEY', 'default');

Setting Environment Variables

To set the value of an environment variable, use the set method:

$editor->set('KEY', 'value');

Saving Changes

After modifying the environment variables, you need to save the changes back to the .env file:

$editor->save();

This will overwrite the existing file with the updated variables.

Backup Functionality

By default, the backup functionality is disabled. If you want to enable it, pass true as the second argument when creating the DotenvEditor instance:

$editor = new DotenvEditor('/path/to/.env', true);

This will create a backup file (.env.backup) before saving any changes. The backup file will contain the previous version of the .env file.

Note: The backup file will be overwritten each time you backup the .env file again.

Example

Here's an example of how you can use the DotenvEditor class:

use Redot\DotenvEditor\DotenvEditor;
use Redot\DotenvEditor\Exceptions\FileNotFoundException;

try {
    $editor = new DotenvEditor('/path/to/.env');

    $editor->set('APP_ENV', 'production');
    $editor->set('APP_DEBUG', 'false');

    $editor->save();

    echo 'Changes saved successfully.';
} catch (FileNotFoundException $e) {
    echo 'The file could not be found.';
}

Testing
