How can PHP be used to properly save HTML code in a database without losing content?

When saving HTML code in a database using PHP, it's important to properly escape the content to prevent any data loss or security vulnerabilities. One way to achieve this is by using functions like htmlspecialchars() to encode the HTML content before saving it to the database. This ensures that the HTML tags and special characters are stored correctly and can be safely retrieved later.

// Assume $htmlContent contains the HTML code to be saved in the database

$escapedHtmlContent = htmlspecialchars($htmlContent);

// Now you can safely insert $escapedHtmlContent into the database
