Ftp_login (con,user,password) login ftp,con is an uplink ftp connection. There are also user user and password password

Ftp_close (con) closes the connection to con.

Ftp_pasv (con,true) turns on the passive transfer mode of con. Data is transmitted by the client. Of course, it can only be executed if the login is successful.

Ftp_put (con,remove,local,mode) uploads the file in the local path to con and names it remove file. Mode is the transfer mode (FTP_ASCII,FTP_BINARY)
