Me pasaba algo similar, intenta:
Código PHP:
// MySQL Hostname MySQL User
mysql_connect("localhost","a5333867_Names","password");
// MySQL Database
mysql_select_db("a5333867_Names");
Código PHP:
// BASE Field
$numero = mysql_query("INSERT INTO name (name_sar) values ('$_pst_usuario')");
$query= mysql_query("SELECT MAX(name_sar) AS id FROM name");
while($row = mysql_fetch_array($query)){
$array1 = $row['id'];
}
echo "</br>";
print_r($array1);
echo "</br>";
