Informix ODBC Driver... Invalid connection string attribute? - php

Question

I had never used PDO for to connect with Informix database before, this error poped up while I was running a basic query:
SQLSTATE=01S00, SQLDriverConnect: -11005 [Informix][Informix ODBC Driver]Invalid connection string attribute.
And this is my code:
<?php
class prueba{
private static $cn = null;
public static function conectar(){
if(self::$cn !== null ) {
return self::$cn;
}
try{
self::$cn= new PDO("informix:host=localhost; service=30000;
database=mrroot; server=mrserver; protocol=onsoctcp;
EnableScrollableCursors=1", "mrtony", "");
return self::$cn;
} catch (PDOException $ex){
die($ex->getMessage());
}
}
public static function consulta(){
$query = "SELECT * FROM fr_envio";
$cn = prueba::conectar();
$resultado = $cn->prepare($query);
$resultado->execute();
echo '<table>';
while ($row = $resultado->fetch(PDO::FETCH_ASSOC))
{
echo '<tr>';
echo '<td>'.$row['enviopre'].'</td>';
echo '<td>'.$row['enviofra'].'</td>';
echo '<td>'.$row ['enviopec'].'</td>';
echo '<td>'.$row ['envioval'].'</td>';
echo '</tr>';
}
echo '</table>';
}
}
$prueba = new prueba();
$prueba->consulta();
?>
I've tested the same code on Mysql, just change the connection string, and everything works perfect, it seems like the connection string is missing something, and I dont know what it could be.
I followed what is says in this tutorial:

Ummm... try specifing the connection string in just one line.
root#irk:/usr3/products/php53# cat test.php
<?php
$db = new PDO("informix:host=irk;service=3046;database=stores7;
server=irk1210;protocol=onsoctcp;EnableScrollableCursors=1;", "informix", "ximrofni");
print "Connection Established!\n\n";
$stmt = $db->query("select * from systables");
$res = $stmt->fetch( PDO::FETCH_BOTH );
$rows = $res[0];
echo "Table contents: $rows.\n";
?>
root#irk:/usr3/products/php53# php test.php
PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE=01S00, SQLDriverConnect: -11005 [Informix][Informix ODBC Driver]Invalid connection string attribute.' in /usr3/products/php5/test.php:4
