How to edit and save custom config files in Laravel?

Question

I am creating simple web application in Laravel 4. I have backend for managing applications content. As a part of backend i want to have UI to manage applications settings. I want my configuration variables to be stored in file [FOLDER: /app/config/customconfig.php].

I was wondering if there's any possibility in Laravel how to have custom config file, which can be managed/updated thru backend UI?

Answer 1

I did it like this ...

config(['YOURKONFIG.YOURKEY' => 'NEW_VALUE']);
$fp = fopen(base_path() .'/config/YOURKONFIG.php' , 'w');
fwrite($fp, '<?php return ' . var_export(config('YOURKONFIG'), true) . ';');
fclose($fp);

You'll have to extend the Fileloader, but it's very simple:

class FileLoader extends \Illuminate\Config\FileLoader
{
    public function save($items, $environment, $group, $namespace = null)
    {
        $path = $this->getPath($namespace);

        if (is_null($path))
        {
            return;
        }

        $file = (!$environment || ($environment == 'production'))
            ? "{$path}/{$group}.php"
            : "{$path}/{$environment}/{$group}.php";

        $this->files->put($file, '<?php return ' . var_export($items, true) . ';');
    }
}

Usage:

$l = new FileLoader(
    new Illuminate\Filesystem\Filesystem(), 
    base_path().'/config'
);

$conf = ['mykey' => 'thevalue'];

$l->save($conf, '', 'customconfig');

Based upon @Batman answer with respect to current version (from 5.1 to 6.x):

config(['YOUR-CONFIG.YOUR_KEY' => 'NEW_VALUE']);
$text = '<?php return ' . var_export(config('YOUR-CONFIG'), true) . ';';
file_put_contents(config_path('YOUR-CONFIG.php'), $text);

Afiak there is no built-in functionality for manipulating config files. I see 2 options to achieve this:

• You can store your custom config in your database and override the default config at runtime with Config::set('key', 'value'); But be aware that

Configuration values that are set at run-time are only set for the current request, and will not be carried over to subsequent requests. @see: http://laravel.com/docs/configuration

• Since config files are simple php arrays, it's easy to read, manipulate and write them. So with a little custom code this should be done quickly.

In general I'd prefer the first option. Overriding config files can might cause some troubles when it comes to version control, deployment, automated testing, etc. But as always, this strongly depends on your project setup.

<?php

namespace App\Helpers;

class Uid
{

    // You can simply use this function :
    // you have to stick to using single quotation (')
    public static function setConfig($config,$key,$value,$path)
    {
        file_put_contents(
            $path,
            str_replace("'$key'". ' => ' ."'" . config($config)."'",
            "'$key'". ' => ' ."'" . $value ."'",
            file_get_contents($path))
        );
        // clear config cache
        Artisan::call('cache:clear');
    }
    
    
    // Or use these. It makes no difference if you use a single or double quotation
    public static function setConfig($config,$key,$value,$path)
    {
        file_put_contents(
            $path,
            str_replace(["'$key'". ' => ' ."'" . config($config)."'","\"$key\"". ' => ' ."\"" . config($config)."\""],
            "'$key'". ' => ' ."'" . $value ."'",
            file_get_contents($path))
        );
        // clear config cache
        Artisan::call('cache:clear');
    }


   /*
    * $name => Config Name
    * $key => The key whose value you want to change; Example : 'redis.client'
    * $value => The new value, you can add an array
    * $implodeCharacter => spacers between keys
    */

    public static function putConfig($name,$key,$value,$implodeCharacter = '.' )
    {
        $path = base_path('config/'.$name.'.php');
        $config = config($name);

        $data = self::findAndReplace($key, $config,$value,$implodeCharacter);

        file_put_contents($path,'<?php
        return '.var_export($data,true).';');

        Artisan::call('cache:clear');
    }

    public static function findAndReplace($key, $config,$value,$implodeCharacter) {
        $parts = explode($implodeCharacter, $key);
        for($i=0;$i < count($parts);$i++) {
            if($i == count($parts)-1){
                $config[$parts[$i]] = $value;
            }else{
                $config= $config[$parts[$i]];
            }
        }
        return $config;
    }

}
