How to get user roles in drupal 7.x?

Question

I want to get the user roles Just like getting node types using this

node_type_get_types();

is there anyway to get user roles using a function like this?

Solution 1

See the user_roles() function which provides a list of all roles, or you can optionally filter on specific conditions (there are more details on the documentation page I linked to).

Solution 2

If you want to check for a specific role of the current user (in this example we use "authenticated user"):

global $user;

if (in_array('authenticated user', $user->roles)){
    //do stuff
}

Solution 3

You can use user_load() to retreive the roles for a user.

example:

$user = user_load(1);
$roles = $user->roles;
// $roles contains all the users assigned roles

OP seems to want a list of all roles in the system, not all roles for a particular user
