Laravel is an excellent PHP framework that adopts the MVC (Model-View-Controller) design pattern to make it easier for developers to build web applications. Among them, View is part of the MVC architecture and is used to display the data and user interface of the application. In Laravel, views are typically rendered using the Blade templating engine. However, in some cases, we can also use PHP directly to render the view without using the Blade template engine. This article explains how to use Laravel without the Blade template engine.

Why not use the Blade template engine

Although the Blade template engine is widely used in Laravel, and it has some very useful features, such as template inheritance, conditional statements, loop statements, etc. However, in some cases, we may need to use native PHP to render the view, for example:

Blade syntax is too complex and not easy to read and maintain;
We want We need to use some functions or extensions that come with PHP, but these are not convenient to implement in Blade;
We already have some ready-made PHP view templates and do not want to rewrite them as Blade templates.

In these cases, we can consider not using the Blade template engine and using PHP directly to render the view.

Methods without using the Blade template engine

So, how do we use PHP to render views in Laravel? Two methods will be introduced below.

Using PHP files as views

We can create a PHP file and then use the view() method in the controller to load the file. For example, we create a PHP file named hello.php in the resources/views directory with the following content:

<!DOCTYPE html>
<html>
<head>
    <title>Hello Laravel</title>
</head>
<body>
    <h1>Hello, <?php echo $name; ?>!</h1>
</body>
</html>

Copy after login

Then, in the controller method, We can use the following code to load this view:

public function hello()
{
    $name = 'Laravel';
    return view('hello', ['name' => $name]);
}

Copy after login

In this example, we use the view() method to load the hello.php file and add a The variable $name is passed to the view.

Output HTML directly in the controller

In addition to using PHP files as views, we can also output HTML code directly in the controller. For example:

public function hello()
{
    $name = 'Laravel';
    $html = '<!DOCTYPE html>
             <html>
             <head>
                 <title>Hello Laravel</title>
             </head>
             <body>
                 <h1>Hello, ' . $name . '!</h1>
             </body>
             </html>';
    return response($html);
}

Copy after login

In this example, we define an HTML string directly in the controller method and return it as the response.

Summary

The Blade template engine is a major feature of Laravel, but in some special cases, we can also use native PHP to render views instead of the Blade template engine. This article describes two methods that don't use the Blade template engine, using PHP files as views and outputting HTML code directly in the controller. Of course, which method to use still depends on the specific situation.
