Phpsocket programming communication today finally tested the socket communication in php. first look at the schematic diagram.
Here we can clearly see the position of the socket in the network model and the Port image.
Our programming is in this order. please refer to the figure below.
Now let's write a program. let's first check whether the Server is saved as serverSocket. php.
[Php] view plain copy print?
The code of the Client client is saved as Client. php.
[Php] view plain copy print?
Note: 1 when testing the socket, you must check whether you have enabled the socket extension Library. if you have not found extension_dir = php_sockets.dll in php. ini, remove the semicolon.
2. during the test, enter http: // localhost/serverSocket in the browser. php and http: // localhost/client. php: Now the question is, which one should be run first? because the client needs to respond, we should first run the server and then run the client, so that you can see the result.
Socket function reference
Socket_accept () accepts a Socket connection
Socket_bind () binds the socket to an IP address and port.
Socket_clear_error () clears socket errors or the final error code
Socket_close () closes a socket resource
Socket_connect () starts a socket connection
Socket_create_listen () opens a socket listener on the specified port.
Socket_create_pair () generates a pair of non-differentiated sockets into an array.
Socket_create () generates a socket, which is equivalent to the data structure of a socket.
Socket_get_option () obtain the socket option
Socket_getpeername () obtains the IP address of a remote host similar to that of a remote host.
Socket_getsockname () gets the IP address of the local socket
Socket_iovec_add () add a new vector to a scattered/aggregated array
Socket_iovec_alloc () this function creates an iovec data structure that can send and receive read/write data.
Socket_iovec_delete () deletes an allocated iovec
Socket_iovec_fetch () returns the data of the specified iovec resource.
Socket_iovec_free () releases an iovec resource.
Socket_iovec_set () sets the new value of iovec data
Socket_last_error () obtains the final error code of the current socket.
Socket_listen () listens to all connections from the specified socket
Socket_read () reads data of the specified length
Socket_readv () reads data from scattered/aggregate arrays
Socket_recv () ends data from the socket to the cache
Socket_recvfrom () accepts data from the specified socket. If no value is specified, the current socket is used by default.
Socket_recvmsg () receives messages from iovec
Socket_select () multi-path selection
Socket_send () this function sends data to the connected socket
Socket_sendmsg () sends a message to the socket
Socket_sendto () sends a message to the socket of the specified address
Socket_set_block () is set to block mode in socket
Set the socket in socket_set_nonblock () to non-block mode.
Socket_set_option () sets socket options
Socket_shutdown () function allows you to close the read, write, or specified socket
Socket_strerror () returns a detailed error of the specified error number.
Socket_write () writes data to the socket cache
Socket_writev () writes data to a distributed/aggregate array
