Laravel .env editor

Installation

composer require dacoto/laravel-env-set

Usage

Working with facade

Laravel Set Env has a facade with the name dacoto\EnvSet\Facades\EnvSet. You can perform all operations through this facade.

Example:

<?php namespace Your\Namespace;

// ...

use dacoto\EnvSet\Facades\EnvSet;

class YourClass
{
    public function yourMethod()
    {
        EnvSet::doSomething();
    }
}

Using dependency injection

This package also supports dependency injection. You can easily inject an instance of the dacoto\EnvSet class into your controller or other classes.

Example:

<?php namespace App\Http\Controllers;

// ...

use dacoto\EnvSet;

class TestEnvSetController extends Controller
{
    protected $editor;

    public function __construct(EnvSet $editor)
    {
        $this->editor = $editor;
    }

    public function doSomething()
    {
        $editor = $this->editor->doSomething();
    }
}

Reading file content

Reading raw content.

Method syntax:

/**
 * Get raw content of file
 *
 * @return string
 */
public function getContent();

Example:

$rawContent = EnvSet::getContent();

Reading content by lines.

Method syntax:

/**
 * Get all lines from file
 *
 * @return array
 */
public function getLines();

Example:

$lines = EnvSet::getLines();

Note: This will return an array. Each element in the array consists of the following items:

• Number of the line.
• Raw content of the line.
• Parsed content of the line, including: type of line (empty, comment, setter...), key name of setter, value of setter, comment of setter...

Reading content by keys

Method syntax:

/**
 * Get all or exists given keys in file content
 *
 * @param  array  $keys
 *
 * @return array
 */
public function getKeys($keys = []);

Example:

// Get all keys
$keys = EnvSet::getKeys();

// Only get two given keys if exists
$keys = EnvSet::getKeys(['APP_DEBUG', 'APP_URL']);

Note: This will return an array. Each element in the array consists of the following items:

• Number of the line.
• Key name of the setter.
• Value of the setter.
• Comment of the setter.
• If this key is used for the "export" command or not.

Determine if a key exists

Method syntax:

/**
 * Check, if a given key is exists in the file content
 *
 * @param  string  $keys
 *
 * @return bool
 */
public function keyExists($key);

Example:

$keyExists = EnvSet::keyExists('APP_URL');

Get value of a key

Method syntax:

/**
 * Return the value matching to a given key in the file content
 *
 * @param  $key
 *
 * @throws \dacoto\EnvSet\Exceptions\KeyNotFoundException
 *
 * @return string
 */
public function getValue($key);

Example:

$value = EnvSet::getValue('APP_URL');

Note: To apply the changes to the file, you have to save it with the save method.

Writing content into a file

To edit file content, you have two jobs:

• First is writing content into the buffer
• Second is saving the buffer into the file

Add an empty line into buffer

Method syntax:

/**
 * Add empty line to buffer
 *
 * @return EnvSet
 */
public function addEmpty();

Example:

$file = EnvSet::addEmpty();

Add a comment line into buffer

Method syntax:

/**
 * Add comment line to buffer
 *
 * @param object
 *
 * @return EnvSet
 */
public function addComment($comment);

Example:

$file = EnvSet::addComment('This is a comment line');

Add or update a setter into buffer

Method syntax:

/**
 * Set one key to buffer
 *
 * @param string       $key      Key name of setter
 * @param string|null  $value    Value of setter
 * @param string|null  $comment  Comment of setter
 * @param boolean      $export   Leading key name by "export "
 *
 * @return EnvSet
 */
public function setKey($key, $value = null, $comment = null, $export = false);

Example:

// Set key ENV_KEY with empty value
$file = EnvSet::setKey('ENV_KEY');

// Set key ENV_KEY with none empty value
$file = EnvSet::setKey('ENV_KEY', 'anything-you-want');

// Set key ENV_KEY with a value and comment
$file = EnvSet::setKey('ENV_KEY', 'anything-you-want', 'your-comment');

// Update key ENV_KEY with a new value and keep earlier comment
$file = EnvSet::setKey('ENV_KEY', 'new-value-1');

// Update key ENV_KEY with a new value, keep earlier comment and use 'export ' before key name
$file = EnvSet::setKey('ENV_KEY', 'new-value', null, true);

// Update key ENV_KEY with a new value and clear comment
$file = EnvSet::setKey('ENV_KEY', 'new-value-2', '', false);

Add or update multi setter into buffer

Method syntax:

/**
 * Set many keys to buffer
 *
 * @param  array  $data
 *
 * @return EnvSet
 */
public function setKeys($data);

Example:

$file = EnvSet::setKeys([
    [
        'key'     => 'ENV_KEY_1',
        'value'   => 'your-value-1',
        'comment' => 'your-comment-1',
        'export'  => true
    ],
    [
        'key'     => 'ENV_KEY_2',
        'value'   => 'your-value-2',
        'export'  => true
    ],
    [
        'key'     => 'ENV_KEY_3',
        'value'   => 'your-value-3',
    ]
]);

Alternatively, you can also provide an associative array of keys and values:

$file = EnvSet::setKeys([
    'ENV_KEY_1' => 'your-value-1',
    'ENV_KEY_2' => 'your-value-2',
    'ENV_KEY_3' => 'your-value-3',
]);

Delete a setter line in buffer

Method syntax:

/**
 * Delete on key in buffer
 *
 * @param  string  $key
 *
 * @return EnvSet
 */
public function deleteKey($key);

Example:

$file = EnvSet::deleteKey('ENV_KEY');

Delete multi setter lines in buffer

Method syntax:

/**
 * Delete many keys in buffer
 *
 * @param  array $keys
 *
 * @return EnvSet
 */
public function deleteKeys($keys = []);

Example:

// Delete two keys
$file = EnvSet::deleteKeys(['ENV_KEY_1', 'ENV_KEY_2']);

Save buffer into file

Method syntax:

/**
 * Save buffer to file
 *
 * @return EnvSet
 */
public function save();

Example:

$file = EnvSet::save();
