On the basis of our customers requests, we have installed the PHP socket extension on all our web hosting servers to provide PHP socket programmers with a low-level interface for network communication purposes.
PHP sockets are fundamental end-points that allow clients and servers to communicate in a networked environment. They create an end-to-end communication channel where a client sends requests to a server, which receives them and responds back in return.
For instance, when you type www.google.com in your web browser, it opens a socket (usually on port 80) and connects to the web server to deliver the page to you. The same holds true for any chat client like gTalk or Skype, for example.
Up until now, we have supported functions like fsockopen() for network communication purposes. With the installation of the PHP socket extension, developers will be able to use an array of more complicated functions that will offer them a greater flexibility in establishing a socket-based client-server communication over TCP/IP and in building simple, PHP-based, client-server network applications.
Here is a list of the main low-level-interface functions for creating and manipulating socket communications that are now supported on our servers:
Those of you who are unfamiliar with socket programming can find a lot of useful information on the Unix Socket FAQ page. With slight modifications, this information is fully applicable to socket programming in PHP.

Here is a list of the main low-level-interface functions for creating and manipulating socket communications that are now supported on our servers:
- socket_accept accepts a connection on a socket
- socket_bind binds a name to a socket
- socket_clear_error clears an error on the socket
- socket_close closes a socket resource
- socket_cmsg_space calculates the size of the message buffer
- socket_connect starts a connection on a socket
- socket_create_listen opens a socket on a port
- socket_create_pair creates a pair of indistinguishable sockets and stores them in an array
- socket_create creates a socket
- socket_get_option gets socket options for the socket
- socket_getpeername queries the remote side of the given socket;
- socket_getsockname queries the local side of the given socket;
- socket_import_stream imports a stream
- socket_last_error returns the last error on a socket
- socket_listen listens for a connection on a socket
- socket_read reads the maximum length of bytes from a socket
- socket_recv receives data from a connected socket
- socket_recvfrom receives data from a socket
- socket_recvmsg reads a message
- socket_select runs the select() system call on the given arrays of sockets with a specified timeout
- socket_send sends data to a connected socket
- socket_sendmsg send a message
- socket_sendto sends a message to a socket
- socket_set_block sets blocking mode on a socket resource
- socket_set_nonblock sets a file descriptor to non-blocking mode
- socket_set_option sets socket options for the socket
- socket_shutdown shuts down a socket for receiving, sending, or both
- socket_strerror returns a string, which describes a socket error
- socket_write writes to a socket
