Laravel Application Helper: abort_unless

abort_unless($boolean, $code, $message = '', array $headers)

The abort_unless helper is the logical opposite of the abort_if helper function. Like abort (discussed in the Laravel Application Function: abort article) and abort_if (discussed in the Laravel Application Helper: abort_if article), the abort_unless helper function has the potential to abort the executed of the running application.

From the Laravel Application Helper: abort article.

The abort function will throw an instance of Symfony\Component\HttpKernel\Exception\HttpException with the given $code, $message and any $headers supplied. These exceptions can be caught and handled through the application's kernel.

If the argument supplied for $boolean evaluates to false, the abort_unless function will abort execution of the application.

The following example assumes that some $user object exists with the property admin. The example will check to make sure that the admin property is true. If not, the code will abort with a 401 (unauthorized access) error code.

3abort_unless($user->admin, 401);
