UBB.Developers Forums Community Development Programming PHP and Server-side Scripting Need Some Info

I am reading through the code for UBBThreads trying to get a handle on what is happening where and why. I think I am getting a grasp on what I would need to do to implement the changes I want to make, but one particular line of code is puzzling me.

$dbh -> do_query($query);

Someone please tell me what the hell -> does ! I have searched high and low in my Wrox Beginning PHP4 book, as well as Zend manual and the PHP site. I see it in code returned from search results and am totally in the dark.

Thanks for your time.

That's calling a function that's inside the dbh class.


<?
class someclass {

function somefunction() {


return "someresult";


}

}


$someclass= new someclass;
$thistext = $someclass -> somefunction();

echo $thistext;

?>





The above code should display "someresult" to the browser.






Edit Note: I changed "blah" to "someresult" as what is returned by the function "somefunction()" from inside the class "someclass".

The dbh class is defined in mysql.inc.php in case you want to look at it.

Ahhh...excellent! Makes alot of sense now . Thanks guys.

Ok, this made good sense and answered most of my looming questions....but one I cannot seem to figure out.

I see that the function do_markup() is part of the html class in ubb.inc.php. From trying to follow the program logic (and yes, it was nearly impossible without your earlier answer) I see that showflat.php and showthreaded.php are what generate the page to view any specific message(s), correct?

My question is this, I cannot seem to determine at what point do_markup which decides wether to 'allowimages' or not interepret the tags. When does this function get called? The only place I haven't looked yet is in the template file....maybe I should look there also. *sigh*

Markup is changed to html when the post is being added to the database (addpost.php) provided the board the post is being assigned to allows markup.

This keeps showflat/showthreaded from having to convert the markup each time a post is displayed.

Well if that just don't friggin beat all ! Well, at least I know now. Appreciate your help.

Thanks.

I learned something too.
