如何在2次运行后暂停循环，在两次之间插入代码，然后继续循环停止？

Question

I currently have a loop of items being shown on a page.

I would like to run the loop twice (output 2 results/items), and THEN insert a banner ONCE right after the 2nd result, and THEN let loop continue from where it left off.

An illustration below:

{--- START OF LOOP ---}

ITEM 1 | ITEM 2
{ BANNER HERE }
ITEM 3 | ITEM 4
ITEM 5 | ITEM 6
ITEM 7 | ITEM 8

{--- END OF LOOP ---}
<- prev | next ->

The items are inside a while loop:

$sql = mysql_query("SELECT id, img, description, keyword, category FROM images WHERE connect = 1 ORDER BY id DESC LIMIT $from , $perPage");

while($result = mysql_fetch_object($sql)) {
LOOP OF ITEMS HERE }

I've only ever found "do" / "while" methods, which isn't really what I'm looking for. If anyone could help, thank you for your time & assistance.

Answer 1

$i=1;
while($result = mysql_fetch_object($sql)) {
    //print item
    if($i==2) { 
        //print banner
    }
    $i++;
}

if you want it to print every 2 items the yu can use

if($i % 2 == 0)
