If you’re selling infoproducts on WordPress—like online courses, eBooks, coaching services, or membership communities—a little knowledge of PHP can go a long way. PHP is the programming language that powers WordPress, making it the backbone of your site’s functionality. Understanding its basics can help you customize your store, enhance customer experiences, and boost your sales. In this beginner’s guide, we’ll break down what PHP is, how it works with WordPress, and how you can use it to succeed in selling infoproducts.
What is PHP?
PHP stands for Hypertext Preprocessor, and it’s a server-side scripting language designed for web development. In simple terms, PHP runs on your web server and tells WordPress what to do—like displaying your product pages, processing orders, or showing customer dashboards. For infoproduct sellers, PHP is what makes your site dynamic, letting you go beyond static content to create a tailored, interactive shopping experience.
Think of it as the engine under WordPress’s hood—without PHP, your site would just be a pretty shell with no power to sell or deliver your digital goods.
How PHP Works with WordPress
WordPress is built on PHP, and almost every file in your site uses it—from themes to plugins to the core software itself. When a customer visits your site, PHP code runs on the server to fetch data (like your course listings from the database), process it (like calculating a discount), and send it to their browser as a finished page. Here’s how it ties into selling infoproducts:
- Themes: PHP controls how your sales pages look and function.
- Plugins: Tools like WooCommerce or LearnDash use PHP to handle payments or course progress.
- Custom Features: PHP lets you tweak your site to fit your business needs.
For example, when someone buys your eBook, PHP handles adding it to their cart, processing the payment, and delivering the download link—all behind the scenes.
Why PHP Matters for Infoproduct Success
You don’t need to be a coding pro to see PHP’s value—it’s about small changes that make a big impact. Here’s why it’s key for selling infoproducts:
Customize Your Store
Out-of-the-box WordPress is great, but PHP lets you tailor it. Want a unique checkout button or a special discount for coaching clients? PHP makes it happen, setting your site apart and boosting conversions.
Improve User Experience
A smooth, personalized experience keeps customers buying. PHP can show related products—like suggesting a course after an eBook purchase—or tweak your site to load faster, keeping buyers happy.
Solve Problems Fast
When something breaks—like a product not displaying—knowing PHP helps you spot and fix it quickly, avoiding lost sales and frustrated customers.
Scale Your Business
As your infoproduct lineup grows, PHP lets you add custom features without relying on expensive plugins, keeping your site lean and your profits high.
PHP Basics for Beginners
Let’s dip into some PHP essentials you can use right away. Don’t worry—it’s simpler than it looks!
Understanding Syntax
PHP code lives inside <?php and ?> tags. Here’s a basic example:
<?php
echo "Welcome to my infoproduct store!";
?>This prints a message on your site—think of it as a hello to your customers.
Variables
Variables store data, like a product price:
<?php
$price = 49.99;
echo "This course costs $price!";
?>You could use this to display dynamic prices on your sales page.
Functions
Functions are reusable bits of code. WordPress has tons built in, like get_the_title() to show a product’s name:
<?php
echo get_the_title();
?>Add this to a page to display your course or eBook title automatically.
Where to Add PHP
Use your theme’s functions.php file or a custom plugin to add code safely. Always back up your site first with a tool like UpdraftPlus, and test changes on a staging site.
Practical PHP Uses for Infoproducts
Here’s how PHP can directly help your sales:
Custom Product Displays
Tweak your shop page to highlight best-sellers:
<?php
if ( get_post_meta( get_the_ID(), 'is_bestseller', true ) ) {
echo '<span class="bestseller">Top Pick!</span>';
}
?>Add this to your theme to flag popular courses or downloads.
Dynamic Discounts
Offer a timed deal on coaching sessions:
<?php
$original_price = 200;
$discount = 0.2; // 20% off
$sale_price = $original_price * (1 - $discount);
echo "Limited Offer: Now only $$sale_price!";
?>This could draw in more buyers with a sense of urgency.
Personalized Messages
Greet returning customers:
<?php
if ( is_user_logged_in() ) {
$user = wp_get_current_user();
echo "Welcome back, " . $user->display_name . "!";
}
?>This builds rapport, encouraging repeat purchases.

How PHP Boosts Infoproduct Sales
Imagine a customer lands on your site. A PHP tweak shows them a “Best Seller” badge on your top course, grabbing their attention. Another snippet applies a quick discount at checkout, sealing the deal. A third greets them by name when they log in for their download, making them feel valued. These little touches—powered by PHP—turn browsers into buyers and one-time shoppers into regulars.
