need help about function

plz look at these 3 types of code

type 1:

PHP Code:


		
			
$query = $vbulletin->db->query_first("SELECT * FROM " . TABLE_PREFIX . "table");



function abc($var)

{

echo $query[$var];

}

type 2:

PHP Code:


		
			
function abc($var)

{

global $vbulletin;

$query = $vbulletin->db->query_first_slave("SELECT * FROM " . TABLE_PREFIX . "table");

echo $query[$var];

}

type 3:

PHP Code:


		
			
$query = $vbulletin->db->query_first("SELECT * FROM " . TABLE_PREFIX . "table");



function abc($var)

{

global $query;

echo $query[$var];

}

i tried all 3 of those....type 1 didn't work. type 2 & 3 work

but i dont want to use type 2....coz everytime i use that function it will connect to DB & waste a lot of resource. if i use this function 10 times in a page, it will connect to DB 10 times....too bad!

but not sure about type 3....what about it? is it waste resource like type 2 ??

I'm not sure many people would know the answer to that, I know I don't... Sorry, but be patient someone might :)

I don't understand what you are trying to do, so I can't really help. It's hard to look at such a general piece of code and make comments. All I can say is I wouldn't go for number 2. I wouldn't really go for any of them since you are grabbing the whole table. I would think you would only need some of it.

ok, in a page im using a function more than 10 times.

inside that function i need to call a DB table. yes lynne u r right, i dont wanna use Type-2 too.

but what about type-3 ?

when declare global $query....i just want to know, is it connect to DB everytime u use that function in this case or not.

Type 3 should not be connecting to the database everytime the function is called. However, I have to wonder why you are using a function just to spit something out. That seems unnecessary.
