When it comes to throwing an HTTP exception when a condition is not passed, the best way is to use the abort_if() method.

What is the abort_if() method?

The abort_if() method is a method that renders an exception handler if the condition you passed fails.

Syntax

abort_if(! Auth::user(), 403);

Parameter

This method receives four parameters:

1. The condition
2. The error code you want to display
3. Message (optional)
4. Headers (optional)

Example

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

Output
