Laravel如何使用輔助函數

新增bootstrap/helpers.php檔案

composer.json修改：

"autoload": {
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/"
        },
        "files": [
            "bootstrap/helpers.php"
        ]
    },
           

運作

composer dumpautoload
