WordPress edit admin menu

function edit_admin_menu() {

	global $menu;



	//echo '<br> menu:<pre>';

	//print_r( $menu );

	//echo '</pre_>';

	

	remove_menu_page( 'edit.php' ); // remove posts item

	remove_menu_page( 'edit.php?post_type=page' ); // remove pages item

	remove_menu_page( 'edit-comments.php' ); // remove comments item

	remove_menu_page( 'themes.php' ); // remove themes item

	remove_menu_page( 'plugins.php' ); // remove plugins item

	remove_menu_page( 'tools.php' ); // remove tools item

	remove_menu_page( 'options-general.php' ); // remove options item

}

add_action( 'admin_init', 'edit_admin_menu' );

But user still can visit removed links but entering address manually.
