FTP Functions

Introducere

The functions in this extension implement client access to file servers speaking the File Transfer Protocol (FTP) as defined in » https://www.faqs.org/rfcs/rfc959. This extension is meant for detailed access to an FTP server providing a wide range of control to the executing script. If you only wish to read from or write to a file on an FTP server, consider using the ftp:// wrapper with the filesystem functions which provide a simpler and more intuitive interface.
