本文介绍了一种PHP脚本中检查用户是否拥有特定角色的方法，并提供了一个实用的函数user_has_role()来实现这一功能。

<?php
  global $user;

  // Check to see if $user has the administrator role.
  if (in_array('administrator', array_values($user->roles))) {
    // Do something.
  }
?>

<?php
/**
* Check to see if a user has been assigned a certain role.
*
* @param $role
*   The name of the role you're trying to find.
* @param $user
*   The user object for the user you're checking; defaults to the current user.
* @return
*   TRUE if the user object has the role, FALSE if it does not.
*/
function user_has_role($role, $user = NULL) {
  if ($user == NULL) {
    global $user;
  }

  if (is_array($user->roles) && in_array($role, array_values($user->roles))) {
    return TRUE;
  }

  return FALSE;
}
?>
