PHP function reference using args - php

Question

I'm new to PHP. I'm trying to hide certain dashboard nav items from certain users (editors). I've added this to the functions, which has hidden it for all users:
<?php
function remove_menus(){
remove_menu_page( 'edit-comments.php' ); //Comments
}
add_action( 'admin_menu', 'remove_menus' );
?>
It says here you can use 'current_user_can' to pinpoint certain users but I'm unsure how to use both together.
So far I've tried:
function remove_menus(){
current_user_can(
remove_menu_page( 'editor', 'edit-comments.php' ); //Comments
) );
}
and
function remove_menus(){
current_user_can( array(
remove_menu_page( 'editor', 'edit-comments.php' ); //Comments
) );
}
..but from looking at other functions, they seem to in brackets with => inbetween so I'm presuming I'm using this function the wrong way.
Any help would be appreciated, thanks.

First answer, very simple , use logic "OR" operator:
<?php
function remove_menus(){
if( current_user_can('editor') || current_user_can('administrator') ) { // stuff here for admins or editors
remove_menu_page( 'edit-comments.php' ); //stuff here for editor and administrator
}
} ?>
If you want to check more than two roles, you can check if the roles of current user is inside an array of roles, something like:
<?php
function remove_menus(){
$user = wp_get_current_user();
$allowed_roles = array('editor', 'administrator', 'author');
if( array_intersect($allowed_roles, $user->roles ) ) {
remove_menu_page( 'edit-comments.php' ); //stuff here for allowed roles
}
} ?>
However, current_user_can can be used not only with users role name, but also with capabilities. So, once both editors and administrators can edit pages, your life can be easier checking for that capabilities:
<?php
function remove_menus(){
if( current_user_can('edit_others_pages') ) {
remove_menu_page( 'edit-comments.php' );// stuff here for user roles that can edit pages: editors and administrators
}
}
?>
Have a look here for more info on capabilities.
