1.创建 app/Helpers/functions.php文件（右键创建）  
2.修改 composer.json文件

“autoload”: \{  
“classmap”: \[  
“database/seeds”,  
“database/factories”  
\],  
“psr-4”: \{  
“App\\”: “app/”  
\},  
/添加的 files 键\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*  
“files”: \[  
“app/Helpers/functions.php” //这个就是第一步创建的文件路径  
\]  
\},

3.执行命令 composer dump-autoload  
4.复制以下代码到functions.php，或者重新自定义
