In what ways can PHP beginners improve their understanding of user rights management in scripts and prevent issues like missing admin permissions?

One way PHP beginners can improve their understanding of user rights management in scripts and prevent issues like missing admin permissions is by implementing role-based access control. This involves assigning roles to users and defining permissions for each role. By checking the user's role and permissions before allowing access to certain parts of the script, you can ensure that only authorized users can perform specific actions.

// Check if user has admin permissions before allowing access
if($user_role === 'admin'){
    // Code to execute if user has admin permissions
    echo "You have admin permissions.";
} else {
    // Code to execute if user does not have admin permissions
    echo "You do not have admin permissions.";
}
