What are the potential issues with using FTP functions in PHP on a shared web hosting environment?

Potential issues with using FTP functions in PHP on a shared web hosting environment include security risks, such as exposing FTP credentials in the code, and potential restrictions imposed by the hosting provider on FTP connections. To mitigate these risks, it is recommended to use secure FTP connections (SFTP) and store FTP credentials securely outside of the code. 

// Example of securely storing FTP credentials outside of the code
$ftp_server = 'ftp.example.com';
$ftp_username = 'your_username';
$ftp_password = 'your_password';
