Question

I’ve written some simple functions for database handling like this:

function dbOpen($db)
{
    $username = "admin";
    $password = "pass";
    $hostname = "localhost";    
    $db = mysql_connect($hostname, $username, $password)
}

function dbClose($db)
{
    mysql_close($db);
}

What I want to do is get access to the variable I passed to the dbOpen function like:

dbOpen($myDB);
$result = mysql_query('SELECT * FROM my_tbl',$myDB);

However, for some reason this function won’t initialize $myDB. Does anyone have any ideas what I’m doing wrong?

If you want to do that, you need to set up your database functions to take that variable passed as a reference. This here explains it.
