Make sure PHP / Mysql always returns utf-8

<?php
header('Content-Type: charset=utf-8'); //At start of page (or at least before any output)

/*Assuming mysql/mysqli connect is set to $connect*/
//MySql
mysql_set_charset('UTF8',$connect);
//MySqli
mysqli_set_charset($connect,'utf8');
?>

//Not needed, but always helpful (placed between <head></head> tags)
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
