Guys im trying to join a comments table to posts table using the following query in a method.

public function feedView($session,$friend,$updateid) {

         $sql2=" select  u.update_body,u.author,u.time,u.title,u.account_name,u.update_id,"
            . "c.comment_body, c.os_id,c.author_c,c.time_c,c.comment_id,c.type_c  "
            . "from updates u join comment_update c "
            . "on c.os_id=:statusid WHERE u.account_name = :session or u.account_name=:friend and (u.type = 'a' or 'c') order by u.time asc,c.time_c desc";

    $stmth=  $this->_db->prepare($sql2);
    $stmth->bindValue(":session",$_SESSION['uname']);
    $stmth->bindValue(":friend",$friend);
    $stmth->bindValue(":statusid",$updateid);
    $stmth->execute();
    return $stmth->fetchAll(PDO::FETCH_ASSOC);
    }

it prints the posts fine but the problem is with comments content where it seems to print the comments in the same posts twice. don't know where the bug is coming from.

here is the DB schema:

here is the code for displaying feeds:-

 <?php
include "includes/dbconfig.inc.php";
    $status&#95;replies="";
       $status&#95;list="";
       $statusui&#95;edit="";
       $isowner="";
       $is&#95;friend="";
       $friends = array();
$stmt=  $conn->prepare("select friend&#95;one, friend&#95;two from friends where "
        . "(friend&#95;one=:session OR friend&#95;two=:session) and accepted='1'");
$stmt->bindparam(":session",$&#95;SESSION['uname']);
$stmt->execute();


foreach ($stmt->fetchAll(PDO::FETCH&#95;ASSOC) as $i=> $r ) {
    $r["friend&#95;one"] == $&#95;SESSION['uname'] ? $friends[]= $r["friend&#95;two"] : $friends[] = $r["friend&#95;one"]; 
$friend=$friends[$i];
//fetch update&#95;id from user table in db and inject it to the feed query.
$status2view=$project->statusView($&#95;SESSION['uname']);
foreach ($status2view as $val) {
   $updateid=$val['update&#95;id'];

//select all relevant posts and comments using the following query and print it.
$feedView=$project->feedView($&#95;SESSION['uname'],$friend,$updateid);

          foreach  ($feedView as $row1) {

                $status&#95;reply&#95;id=$row1['comment&#95;id'];
                $reply&#95;d=htmlentities($row1['comment&#95;body']);
                $reply&#95;data=  stripslashes($reply&#95;d);
                $reply&#95;osid=$row1['os&#95;id'];
                $reply&#95;date=$row1['time&#95;c'];
                $reply&#95;author=$row1['author&#95;c'];
                $updateid=$row1['update&#95;id'];
                $account&#95;name=$row1['account&#95;name'];
                $os&#95;id=$row1['os&#95;id'];
                $author=$row1['author'];
                $post&#95;date=$row1['time'];
                $title= stripslashes($row1['title']);
                $data= stripslashes($row1['update&#95;body']);
                $statusdeletebutton='';     
                $reply&#95;delete&#95;button="";
        if ($reply&#95;author==$&#95;SESSION['uname'] ) {
                   $reply&#95;delete&#95;button="<li><a href='#'type='".$status&#95;reply&#95;id."' class='delete&#95;reply&#95;btn glyphicon glyphicon-trash delete&#95;reply&#95;".$status&#95;reply&#95;id."' title='Delete this comment'> Remove</a></span></li>";
