require 'config.php';
$query = "SELECT * FROM `posts` ORDER BY `id` DESC LIMIT 8";
$do = mysqli_query($con, $query) ;
while ($result = mysqli_fetch_assoc($do)){
$query="SELECT * FROM `lang` where id='$result[langid]'";
$do1=mysqli_query($con,$query);
$query="SELECT * FROM `users` where id='$result[userid]'";
$do2=mysqli_query($con,$query);
$String=$result['titel'];
$text_length = 30; // طول الحروف المراد ظهورها
if (strlen($String) > $text_length) {
// اذا كان طول النص اكبر من النص المراد ظهورة نفذ التالي
$String = substr($String, 0, 33);
// قص من النص التالي ما بعد الرقم في المتغير الخاص بطول الحروف المراد ظهورها
$String .= " ...";
// اضف إلى النص بعد ارجاعه هذه النقاط

You are doing several queries, but looping only on the last one which is SELECT * FROM 'users' where id='$result[userid]', and it sounds like this query is going to give you a single result. (A single user)
You can either store the results of each queries, and use them all in a single loop later on, or join your tables to get all the data you want from a single query.
