Creating the New Role

$result = add_role(
    'Role Slug', // Ex. customer_role
    __( 'Role Label' ), // Customer Role
    array(
        'read'         =&gt; true,  // true allows this cappability
        'edit_posts'   =&gt; true,
        'delete_posts' =&gt; false, // Use false to explicitly deny
    )
);

if ( null !== $result ) {
    echo 'New Role Created!';
}
else {
    echo 'Opps!! the Role already exists.';
}
