I'm trying to get my head around this with classes. What I'm trying to do is use one class's functions within another class. Probably easier if I just show some code:
And my index file looks like this at the top:
function DB($host, $db_user, $db_pswd, $db_name, $db_prefix)
$open = mysql_connect($host, $db_user, $db_pswd)
or die('Unable to connect');
$db = mysql_select_db($db_name, $open);
// Set the prefix var
$this->prefix = $db_prefix;
return $db->prefix; // Here lies the problem!
Now, I can access the DB class just fine, everything works alright with the $db variable etc, but what I don't understand is how I can use DB within my new Test class. The error generated is a "Call to a member function on a non-object" on the row where I try to do this.
$db = new DB($host, $db_user, $db_pswd, $db_name, $db_prefix);
$test = new Test();
echo $db->prefix; // Works!
echo $test->hello(); // Does not work!
