为什么在回显变量时，替换字符会不断出现？

Question

I'm creating a test application and keeping the name of the person who is taking it on a table, along with the answers. The problem lies when I enter the following characters

á é í ó ú ñ

I've tried some methods (like iconv function) but still not working.

//A sample of the code

require('../connect_db.php');
setlocale(LC_ALL,"es_ES");
mysql_query("SET NAMES 'utf8'");

$sql  =  "SELECT *
          FROM database.test";
$result     = mysql_query($sql) or die (mysql_error());
$row        = mysql_fetch_array($result);
$name      = utf8decode($row[1]);

echo mb_detect_encoding($name); //Just to test
echo $name;

The result:

UTF-8 G�mez

Edit: The problem is not on the database. I've manually entered names with these characters with no problem, so it must be the code.

Answer 1

SOLVED

There was no need to run the first utf8decode() when assigning values to $name

Instead I just called the function at the echo
