How can PHP beginners avoid parse errors when inserting HTML content into a PHP file?

PHP beginners can avoid parse errors when inserting HTML content into a PHP file by properly escaping the HTML content using the `echo` or `print` statements. This ensures that the HTML content is treated as a string and not parsed as PHP code. Additionally, using single quotes for HTML attributes and double quotes for PHP strings can help prevent syntax errors.

<?php
$html_content = "<h1>Hello, World!</h1>";
echo $html_content;
?>
