Default Is this safe?

I'm making an ajax autocomplete search and I want to make sure the server side is safe.

Is there anything wrong with this?

PHP Code:
<?php
// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~ E_NOTICE);

// #################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT''ajax_search');
define('CSRF_PROTECTION'true);
define('LOCATION_BYPASS'1);
define('NOPMPOPUP'1);

// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array();

// get special data templates from the datastore
$specialtemplates = array();

// pre-cache templates used by all actions
$globaltemplates = array();

// ######################### REQUIRE BACK-END ############################
require_once ('./global.php');
$vbulletin->input->clean_gpc('r''q'TYPE_STR);
$query $_REQUEST['q']; 

if(
strlen($query) >= 3){
    
$results $vbulletin->db->query_read("SELECT `query` FROM `search` WHERE `query` LIKE '$query%' LIMIT 1");
    
$result $vbulletin->db->fetch_array($results);
    echo 
$result[query];
}
?>
