Render(), when applied to a view, will generate the corresponding raw html and store the result in a variable.
Render()，当应用于视图时，将生成相应的原始 html 并将结果存储在变量中。
Typical reasons for which I use render are:
我使用渲染的典型原因是：
When converting pages to pdf (ex. using dompdf, pass this into loadhtml()), returning HTML content to ajax calls
将页面转换为 pdf 时（例如使用 dompdf，将其传递给loadhtml()），将 HTML 内容返回给 ajax 调用

Given that you've tagged the question with Blade, I'll assume you mean render inside Laravel's View class.
鉴于您已经用 Blade 标记了问题，我假设您的意思是在 Laravel 的 View 类中渲染。
Illuminate\View\View::render()returns the string contents of the view. It is also used inside the class' __toString()method which allows you to echo a View object.
Illuminate\View\View::render()返回视图的字符串内容。它也在类的__toString()方法中使用，该方法允许您回显 View 对象。
// example.blade.php
Hello, World!
// SomeController.php
$view = view('example');
echo $view->render(); // Hello, World!
echo $view; // Hello, World!
Laravel typically handles this for you, I.e. calls render or uses the object as a string when necessary.
Laravel 通常会为您处理这个问题，即在必要时调用 render 或将对象用作字符串。
Blade's @include('viewname') directive will load the view file and call the render method behind the scenes for example.
例如，Blade 的 @include('viewname') 指令将加载视图文件并调用幕后的渲染方法。
You may use it yourself when you want to get the compiled view to perform some subsequent action. Occasionally I have called render explicitly rather than to string if the view itself is causing an exception and in PHP explains
当您想要获得编译后的视图以执行一些后续操作时，您可以自己使用它。有时，如果视图本身导致异常并且在 PHP 中解释，我会显式调用 render 而不是字符串
Fatal error: Method a::__toString() must not throw an exception in /index.php on line 12
致命错误：方法 a::__toString() 不得在第 12 行的 /index.php 中抛出异常
Calling render() in the above case gives a more useful error message.
在上述情况下调用 render() 会给出更有用的错误消息。
