Name
fsockopen
Synopsis
$fd = fsockopen($hostname,$port);
Opens a connection with hostname on port
port and returns a file descriptor associated with
the open connection. If the port number is 0, the hostname will be
considered the filename of a Unix-style socket file on the local
host. In the case of an error, the function returns the following: -3
if the socket could not be created, -4 if the hostname could not be
resolved, -5 if the connection was refused or timed out, -6 if the
fdopen() call failed, or -7 if the setvbuf() call failed.
