I am new to PHP and currently reading the book "PHP for Absolute Beginners". The book is currently teaching about templating and using StdClass() objects to avoid naming conflicts.
I have a template file named page.php and a home page file named index.php.
My page.php code
<?php return "<!DOCTYPE html> <html> <head> <title>$pageData->title</title> <meta http-equiv='Content-Type' content='text/html;charset=utf-8'/> </head> <body> $pageData->$content </body> </html>";
My index.php
<?php
//this correctly outputs any errors
error_reporting( E_ALL );
ini_set("display_errors", 1);
$pageData = new stdClass();
$pageData->title = "Test title";
$pageData->content = "<h1>Hello World</h1>";
$page = include_once "templates/page.php";
echo $page;
The error I received is
Warning: Undefined variable $title
in C:\xampp\htdocs\ch2\templates\page.php on line 5Warning: Undefined variable $content
in C:\xampp\htdocs\ch2\templates\page.php on line 9I don't understand this as this is exactly what the book teaches, any help would be greatly appreciated and if there is a better way to use templates please remember I am a beginner so please Keep it simple!

Your page.php looks a little strange.
returnis not what I use when printing html. Also, you are using php and html in the php tag, which won't work. Try this:You don’t need
echo $pagein your index.php, let page.php do it./EDIT: There was also a typo on line 9:
$pageData->$content;I've corrected it.
