What are some potential issues you might encounter when using FTP functions in PHP?

When using FTP functions in PHP, you might encounter potential issues such as connection failures, authentication problems, or file transfer errors. Connection failures can occur due to network issues, server unavailability, or incorrect FTP server settings. Authentication issues may arise if the provided credentials are incorrect or if the FTP server has strict authentication requirements. File transfer errors can happen if the remote file does not exist, the local file is not readable, or if there are restrictions on file permissions. It's important to handle these issues by validating input, checking return values, and implementing error handling mechanisms to ensure successful FTP operations in PHP.
