What is the best practice for allowing users to delete specific content on a PHP forum without compromising security?

When allowing users to delete specific content on a PHP forum, it is important to implement proper validation and authorization checks to ensure that the user has the necessary permissions to delete the content. One way to do this is by checking the user's credentials and verifying that they are the owner of the content before allowing the deletion to occur. Additionally, it is crucial to sanitize user input to prevent SQL injection attacks and other security vulnerabilities. 

// Check if user has permission to delete the content
if($user->isAdmin() || $content->getOwner() == $user->getId()) {
    // User has permission, proceed with deletion
    $content->delete();
    echo "Content successfully deleted.";
} else {
    // User does not have permission, display an error message
    echo "You do not have permission to delete this content.";
}
