I recently bumped into trifle that bothers me about annotating in Symfony (not sure if it's also pure PHP thing).
New Route annotations looks like this:
#[Route('route', name: 'route_name')]
And when I want the same type of annotation for @throws I can't find any way instead the old type that looks like this:
/**
* @throws Exception
*/
So I want the new type of annotations even for @throws
The main idea behind attributes is to attach static metadata to our code (methods, properties, etc.). These metadata often include concepts such as "configuration". In your example, this attribute setup a route for your framework. With doctrine, you can setup your entity. A few years ago, there are no attributes, so developers used comments to declare them. PHP8 allow us to use attributes. Let's avoid to use comment (@Route).
Throw tag doesn't setup anything in your application. The exception can only be thrown by your code.
/**
* @throws Exception //this line has no impact on your code
*/
#[Route('route', name: 'route_name')] //this line has an impact by setting up your routes
public myAction() {
throw new Exception('foo'); // This line have an impact on your code
}
This is an information for developers (and valuable IDE) to help us to understand the code. So, there is no attribute version of the @Throw tag. @Throw tag "only" is a documentation, a PHPDoc, a comment :) Your code should mix Annotations in comments and Attributes
