如何在 laravel 中添加和更新配置变量

Question

我有一个配置变量文件，我在我的控制器中使用它而不是 mysql 以获得更快的性能。

但我的问题是我只能读取此配置文件，无法添加或更新其中的任何值。

关于如何更新或向该变量文件添加新值的任何建议：

我的变量文件存储在/config/Banners_size.php:

return [
    "normal_x970h90" => [
        'status' => 'enable',
        'value' => '500'
    ],

    "normal_x234h60" => [
        'status' => 'enable',
        'value' => '500'
    ],
]

我的 php 用于向其中添加新数组但不起作用的代码：

    $banners = Config('Banners_size');
    $banner = array(
        $request->input('size') => [
            'status' => $request->input('status'),
             'value' => $request->input('cost')
        ]
    );

   $bannerinfo = array_merge($banners, $banner);

   Config('Banners_size' , $bannerinfo);

Answer 1

配置文件是只读文件，不能以编程方式向其添加参数。

$banners = config('Banners_size');

config('Banners_size' , $bannerinfo);

以上两行，作用相同，都是return Banner_size.

的值

Answer 2

要在运行时设置配置值，将数组传递给配置助手：

config(['app.timezone' => 'America/Chicago']);

注意 - 它不会为下一个请求保留数据

从技术上讲你可以...

//edit config for current runtime
config(['FILE.KEY' => 'NEW_VALUE']);
// open config file for writing
$fp = fopen(base_path() .'/config/FILE.php' , 'w');
// write updated runtime config to file
fwrite($fp, '<?php return ' . var_export(config('FILE'), true) . ';');
// close the file
fclose($fp);
// clear config cache
Artisan::call('cache:clear');

<?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;
    }

}
