In PHP, what are some common methods for allowing website owners to easily update and change text content on their pages without compromising security?

One common method for allowing website owners to easily update and change text content on their pages without compromising security is to store the text content in a separate file or database, and then retrieve and display this content dynamically in the webpage using PHP. This way, the website owner can update the text content in the file or database without needing to directly edit the webpage code, reducing the risk of introducing security vulnerabilities.

<?php
// Retrieve text content from a file
$text_content = file_get_contents('text_content.txt');

// Display the text content on the webpage
echo $text_content;
?>
