How to use custom functions in laravel6

Laravel6 is a widely used PHP framework with the advantages of simplicity, ease of use, flexibility, and efficiency. Compared with other frameworks, the advantage of Laravel6 is that it provides many ready-made functions and tools, allowing developers to complete development tasks more quickly. Among them, using custom functions is a way to make Laravel6 more convenient.

In Laravel6, custom functions can provide developers with a more efficient development method and improve development efficiency when handling common tasks. Here's how to use custom functions.

1. Create a custom function

In Laravel6, we can create a custom function by writing the function code into the existing PHP file. An example is as follows:

 function test(){
    return '这是自定义函数中的测试';
}

In the above example, we created a function named test(), which will return a string "This is a test in a custom function". Please note that we can use this function anywhere in Laravel6.

2. Using custom functions in Laravel6

In Laravel6, we can use custom functions to complete some tasks, such as database queries, generating HTML pages, etc. Here's how to use custom functions in Laravel6.

1. Using custom functions in the controller

We can call custom functions in the controller to complete some tasks. For example, calling the test() function in the controller:

public function index(){
   $data = test();
   return view('index',['data'=>$data]);
}

In the above example, we assign the return value of the test() function to the variable $data and pass it to the view file index.

2. Using custom functions in view files

We can call custom functions in view files to generate HTML pages. For example, calling the test() function in the view file:

   <p> {!! test() !!} </p>

In the above example, we use the view engine of Laravel6 to directly reference the function test() in the HTML page. The result of the function will be output in the form of HTML.

3. Automatically load custom functions

In Laravel6, we can add custom function files to autoload: files in composer.json to automatically load custom functions:

"autoload": {
        "files": [
            "app/Helpers/my-functions.php"
        ]
    }

In the above example, we put the code of the custom function in the my-functions.php file and added the file to the automatic loading mechanism of Laravel6. This way, we can use custom functions directly anywhere.

4. Conclusion

Laravel6 is a powerful framework that provides many tools and functions that are easy for developers to use. By writing custom functions, we can complete development tasks more efficiently. If you want to use a custom function, you can do it as described above. I believe these methods will bring great convenience to your Laravel6 development.
