When doing FTP data collection, you need to use a PHP function ftp_connect, which is to establish a new FTP connection. If you successfully return a connection ID, if you fail, you will return FALSE.
Ftp_connect () opens a FTP connection with the parameter host as the server to connect to. The host should not end with a slash and the front does not need to start with ftp://. The optional parameter port is the port number of the FTP to which you want to connect. If it is not set or 0, the default port 21 will be used to connect.
When I went to execute my program, I found that the error was as follows:
The copy code is as follows:
PHP Warning: ftp_connect (): php_network_getaddresses: getaddrinfo failed:
