When encoding and concatenating URLs in PHP, it is important to ensure data integrity by properly encoding special characters and using functions like urlencode() and rawurlencode(). This helps prevent errors and ensures that the URL is correctly formatted. Additionally, it is recommended to sanitize user input to prevent any malicious code injection.
