Laravel: abort_if vs throw

As we know from the Laravel documentation, we can use abort_if to throw an HTTP exception if a given boolean expression evaluates to true, and throw_if to throw the given exception if a given boolean expression evaluates to true.

The example usages are given as follows:

abort_if(! Auth::user()->isAdmin(), 403);
throw_if(! Auth::user()->isAdmin(), AuthorizationException::class);

Since for the end user both methods will result in an exception, there seems to be no functional difference between them. Or does Laravel handle them differently in different configurations? In what situations would one choose to implement one over the other, or is it a matter of personal taste?

The abort_if function can only throw an HttpResponseException, NotFoundHttpException, or HttpException exception, all of which are http response related. You will most typically see this used in the controller or a middleware, as these are most responsible for the http response.

The throw_if function allows you to specify the specific exception you'd like to throw, and isn't constrained to only http related exceptions. You will see this more in your application/business logic.

CodePudding user response：

The main difference between abort_if and throw_if is that abort_if will throw an HTTP exception while throw_if will throw a custom exception. This means that abort_if is more suitable for situations where you want to return an error with a specific HTTP status code (e.g. 403 Forbidden), while throw_if is more suitable for situations where you want to throw a custom exception with custom logic (e.g. throwing an AuthorizationException).

In terms of practical usage, it really depends on the situation. If you are dealing with HTTP requests and responses, then abort_if is usually the preferred option, as it allows you to return an appropriate HTTP error code. However, if you are dealing with a custom exception, then throw_if is usually the better option, as it allows you to easily handle the custom exception in your application logic.
