What potential pitfalls should be considered when integrating content from a Wordpress blog into another website using PHP?

One potential pitfall when integrating content from a Wordpress blog into another website using PHP is the risk of exposing sensitive information or vulnerabilities from the Wordpress site. To mitigate this risk, it's important to sanitize and validate any data retrieved from the Wordpress site before displaying it on the external website. This can help prevent malicious code injection or other security issues.

// Example code snippet to sanitize and validate data retrieved from a Wordpress blog
$wordpress_content = get_wordpress_content(); // Function to retrieve content from Wordpress blog

// Sanitize and validate the content
$sanitized_content = wp_kses_post($wordpress_content);

echo $sanitized_content; // Display the sanitized content on the external website
