Socket context options — Socket context option listing
Описание
Socket context options are available for all wrappers that work over sockets, like tcp, http and ftp.
Options
- bindto
-
Used to specify the IP address (either IPv4 or IPv6) and/or the port number that PHP will use to access the network. The syntax is ip:port. Setting the IP or the port to 0 will let the system choose the IP and/or port.
Замечание: As FTP creates two socket connections during normal operation, the port number cannot be specified using this option.
