What are the fundamental concepts that beginners should learn before using advanced template features in PHP?

Before using advanced template features in PHP, beginners should first learn the fundamental concepts of PHP programming such as variables, data types, control structures (if statements, loops), functions, and arrays. Understanding these basics will provide a strong foundation for working with more complex template features.

<?php
// Example of using variables in PHP
$name = "John";
$age = 30;

echo "Hello, my name is $name and I am $age years old.";
?>
