problem when runing a funciton

Posted on 16th Feb 2014 07:03 pm by admin

I am trying to connect to database using a funciton in a functions.php

<?php
function connect_db_Blog (){
$con=mysql_connect("localhost","root","");
$db=mysql_select_db("blog",$con);
}
?>
which I then include with
include ("scripts/php_functions.php");

but when I run a code with

connect_db_Blog();

var_dump($db);
if (!$db) {

echo "sorry, cannot connect to database";

} else {
here comes some code..

I get: sorry , cennot connect to database message.

when I listen for $db with
var_dump($db);
I get int(0);
instead of int(1) which is needed to proceed with the code.

If I just try to connect to database without the include I dont get the error message i.e. .
