How can PHP be used to prevent characters from being corrupted when saving HTML pages in a database?

When saving HTML pages in a database using PHP, special characters like quotes and angle brackets can be corrupted if not properly handled. To prevent this, you can use the `htmlspecialchars()` function in PHP to convert these characters into their HTML entities before saving them in the database. This ensures that the HTML code remains intact and is displayed correctly when retrieved from the database.

// Assuming $html contains the HTML content to be saved in the database
$escaped_html = htmlspecialchars($html, ENT_QUOTES, 'UTF-8');

// Save $escaped_html in the database
// Example query: $sql = "INSERT INTO pages (content) VALUES ('$escaped_html')";
