Create a News Feed that displays posts from people they are following - php

Question

I have a code that should check the Database following to find all the people that the current logged in user has followed then it will search the second database posts to find any posts by the people they are following but it currently only shows one post. I know its not very efficient compared to JOIN but I don't fully understand how that works.
Here is a Screenshot of the Database Following it has the user who sent the following request and the user they are following what is it should do is use the session id for the logged in user and find all matching results for the user in the following column and it should take all the results from the column following and search the database post in the column code and echo all the results as the newsfeed.
<?php
$con=mysqli_connect("HOST","USERNAME","PASSWORD","DB");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$myid=$_SESSION['user']['id'];
$result = mysqli_query($con,"SELECT * FROM following WHERE follower='$myid'");
while($row = mysqli_fetch_array($result)) {
$following=$row['following'];
?>
<?php
$con=mysqli_connect("HOST","USERNAME","PASSWORD","DB");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM posts");
while($row = mysqli_fetch_array($result)) {
if ($following==$row['code']){
?>
<div class="content">
<section class="intro">
<h2><?php echo $row['name']; ?> <?php echo $row['lastname']; ?></h2>
<div class="text">
<?php echo $row['post']; ?>
</div>
<?php
}
else{
}
}
mysqli_close($con);
?>
<?php
}
mysqli_close($con);
?>

Because my previouse answer didnt help What do you want to output??
If your database has 3 followers does it have to output this in html?
But this Code will Output All users in your following list Like this..
$result = mysqli_query($con,"SELECT * FROM posts");
echo "<div class='content'> <section class='intro'>";
echo "<h2><a href='/profile/?id=".$row['code']."'>";
while($row = mysqli_fetch_array($result)) {
if ($following==$row['code']){
echo $row['name']." ".$row['lastname']."</a></h2>";
echo $row['post'];
}
echo "<div class='text'>";
echo "</div>";
}
This Code is Outputting this but the Bold text in this example is a link that goes to
/profile/?id=CODEHERE
Steve Jobs <-- is a link (goes to /profile/?id=CODEHERE
The Post text
Johny John
The Post text
Miracle Tru
The Post text
