PHP Socket,server,cient, Analog post

Fsockopen

to Socket Way to open a connection

my most common use is simulation. Post

this is from Xiao Li's excavation. ... Good

as to the simulation Get Way .... Direct file_get_content it's okay. .

Code See back

Stream_socket_client, code See back

this and Fsockopenfsockopen same . to Socket Way to open a connection , just different parameters .

Stream_socket_server

Build a Socket Server End , code See back

if it was built to be TCP of the Server will use stream_socket_accept for communication

if it was built to beUDPof theServerwill useStream_socket_recvfromandStream_socket_sendtofor communication,andStream_socket_serveryou need to add a parameter to theStream_server_bind

  p>

There is also a < Font face= "Times New Roman" >socket extended This is the most basic building of the socket, but from lang=" "en-us" > 5.3.0 pecl

we're not going to introduce you here. .
