My codes work in localhost but this error happens when I upload to a web site.
<?php

$conn = mysql_pconnect($hostname_conn, $username_conn, $password_conn) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db($database_conn, $conn) or die("cannot select Database");
mysql_query("SET NAMES 'UTF8'");
mysql_query("SET CHARACTER SET UTF8");
mysql_query("SET CHARACTER_SET_RESULTS=UTF8");
