display a list/content on a specific blog article page using php

I have got a blog main page and the actual blog articles pages that are stored in a database table and uses a main blog index.php page where all the blog articles are displayed and then the individual blog articles are displayed on a page called viewpost.php and it gets the relevant blog article from the database using id/postSlug so the urls are SEO friendly and not something like id=1 and so on.

I am looking to display some content that uses HTML coding on a specific blog article using php

I thought I could do something like the following but does not display anything

<?  if($row['postSlug'] == 'fake-antivirus-software-scam') { ?>
        <div class="article">
                <div class="text-center">
                    <div class="col-md-12">
                <h3 class="h-lg text-center">Areas <span class="color">We</span> Cover</span></h3>
                    </div>
               
                <div class="col-md-6">   
                <ul class="areaslist">
                <li class="areasitem"><a href="computer-repair-basildon"><span>Basildon</span></a></li>
                <li class="areasitem"><a href="computer-repair-services-pitsea"><span>Pitsea</span></a></li>
                <li class="areasitem"><a href="computer-repair-laindon"><span>Laindon</span></a></li>
                </ul>
                </div>
                   
                    <div class="col-md-6">
                <ul class="areaslist">
                <li class="areasitem"><a href="computer-repair-langdon-hills"><span>Langdon Hills</span></a></li>
                <li class="areasitem"><a href="computer-repair-wickford"><span>Wickford</span></a></li>
                </ul>
                    </div>
                </div>
            </div>
        <?  } ?>

Code (markup):

I have tried the following as well but is not displaying nothing of what I want

<?php if ($postID=="24") echo '<div class="article">
                <div class="text-center">
                    <div class="col-md-12">
                <h3 class="h-lg text-center">Areas <span class="color">We</span> Cover</span></h3>
                    </div>
               
                <div class="col-md-6">   
                <ul class="areaslist">

I have tried to look on Google to find similar coding for what I am looking to do but not had much joy yet, can anyone help please. Thank you in advance

 

I have tried both of them ways and does not display the html list

'fake-antivirus-software-scam' is the postSlug of the blog article so the url is www.it-doneright.co.uk/blog/fake-antivirus-software-scam

 

I have just managed to solve it by using the following code

<?php if($row['postID'] == '24') echo '<div class="article">
                <div class="text-center">
                    <div class="col-md-12">
                <h3 class="h-lg text-center">Areas <span class="color">We</span> Cover</span></h3>
                    </div>
               
                <div class="col-md-6">   
                <ul class="areaslist">
                <li class="areasitem"><a href="computer-repair-basildon"><span>Basildon</span></a></li>
                <li class="areasitem"><a href="computer-repair-services-pitsea"><span>Pitsea</span></a></li>
                <li class="areasitem"><a href="computer-repair-laindon"><span>Laindon</span></a></li>
                </ul>
                </div>
                   
                    <div class="col-md-6">
                <ul class="areaslist">
                <li class="areasitem"><a href="computer-repair-langdon-hills"><span>Langdon Hills</span></a></li>
                <li class="areasitem"><a href="computer-repair-wickford"><span>Wickford</span></a></li>
                </ul>
                    </div>
                </div>
            </div>'; ?>

I now need to get it to show on more than one specific blog post, I tried the following code but that makes it appear on all the blog posts

if($row['postID'] == '24' || '27')

Code (markup):

Sorry managed to get this working with the following code

<?php if($row['postID'] == '24' || $row['postID'] == '28')

Code (markup):

Now I need help with a else statement as on some other specific blog posts, I want to display another bit of content/coding. I tried with the following but get a blank white page, I added in php error reporting but shows no errors, just a blank white page, the coding I currently have is below

<?php if($row['postID'] == '24' || $row['postID'] == '28') { echo '<div class="article">
