LEARN ABOUT PHP
socket-context-options
SOCKET-CONTEXT-OPTIONS(3) 1 SOCKET-CONTEXT-OPTIONS(3)Socket context options - Socket context option listing
Socket context options are available for all wrappers that work over sockets, like tcp, http and ftp.
o $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 for IPv4 addresses, and [ip]:port for IPv6 addresses. Setting the IP or the port to 0 will let the system choose the IP
and/or port.
Note
As FTP creates two socket connections during normal operation, the port number cannot be specified using this option.
o $backlog
- Used to limit the number of outstanding connections in the socket's listen queue.
Note
This is only applicable to stream_socket_server(3).
