【thinkphp】动态更新数据库配置

更新数据库配置, （事例基于t p5.0）

 //更新数据库配置
    public function update_dbconfig()
    {   
        $dbConfig = [
            \'type\'            => \'mysql\',
            \'hostname\'        => \'localhost\',
            \'database\'        => \'laofan\',
            \'username\'        => \'root\',
            \'password\'        => \'root\',
            \'hostport\'        => \'3306\',
        ];
           try {
                //读取系统配置内容
                $dbconfig_path = APP_PATH . \'database.php\';
                $site_conf = htmlentities(file_get_contents($dbconfig_path));
                //替换配置项
                foreach ($dbConfig as $key => $value) {
                    $pats = \'/\\'\' . $key . \'\\'(.*?)\\',/\';
                    $reps = "\'". $key. "\'". "			=> " . "\'".$value ."\',";
                    $site_conf = preg_replace($pats, $reps, $site_conf); // 正则查找然后替换
                }
                if (!file_exists($dbconfig_path)) {
                    mkdir($dbconfig_path, 0777, true);
                }
                $result = file_put_contents($dbconfig_path, stripslashes(htmlspecialchars_decode($site_conf)));    
            } catch (\Exception $e) {
                return json([\'staus\'=>\'1\',\'message\'=>\'配置文件更新失败\']); 
            }
            return json([\'staus\'=>\'2\',\'message\'=>\'配置文件更新完成\']); 
      
    }
