在做FTP资料采集的时候，需要用到一个PHP函数ftp_connect，这个函数是建立一个新的 FTP 连接，如果成功返回一个连接标识，失败则返回 FALSE.
ftp_connect() 打开一个 FTP 连接，参数 host 为要连接的服务器。host 后面不应以斜线结尾，前面也不需要用 ftp:// 开头。可选参数port 为要连接到的 FTP 器的端口号，如果没有设置或者为0，则会使用默认的端口 21 来连接。
当我去执行我的这个程序的时候，发现报错如下：
复制代码 代码如下:PHP Warning: ftp_connect(): php_network_getaddresses: getaddrinfo failed:
经常之后发现是IPtables的问题，于是我开放了FTP的默认端口，于是就能正常使用了。
遇到这种问题要首先检查自己的服务器的服务，其次就是防火墙问题了。
