What are the best practices for handling meta tags in PHP?
When handling meta tags in PHP, it is important to properly sanitize and validate user input to prevent cross-site scripting attacks. One way to do this is by using the htmlspecialchars function to escape special characters. Additionally, it is recommended to set a default value for meta tags in case the user input is empty or malicious.
// Sanitize and validate user input for meta tags
$meta_title = isset($_POST['meta_title']) ? htmlspecialchars($_POST['meta_title']) : 'Default Meta Title';
$meta_description = isset($_POST['meta_description']) ? htmlspecialchars($_POST['meta_description']) : 'Default Meta Description';
// Use the sanitized meta tags in your HTML output
echo "<title>{$meta_title}</title>";
echo "<meta name='description' content='{$meta_description}'>";
