change database from latin1 to UTF8

[emath]

i want to change my database from latin1 to UTF8 , the ALL COLLATION .

i tried the latest version of vCharset and few other stuff like using this code :

PHP Code:

<?php
// Don't forget to enter your db infos.

define('THIS_SCRIPT', 'convert');
require './global.php';

//---------------

header('Content-type: text/plain');

$dbconn = mysql_connect('localhost', 'name, '********' or die( mysql_error() );
mysql_select_db("emath_arielutf");

$sql = "ALTER DATABASE `name` DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci";
$result = mysql_query($sql) or die( mysql_error() );
print "Database changed to UTF-8.\n";

$sql = 'SHOW TABLES';
$result = mysql_query($sql) or die( mysql_error() );

while ( $row = mysql_fetch_row($result) )
{
$table = mysql_real_escape_string($row[0]);
$sql = "ALTER TABLE $table DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci, CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci";
mysql_query($sql) or die( mysql_error() );
print "$table changed to UTF-8.\n";
}

mysql_close($dbconn);
?>
