stream_socket_recvfrom ( resource $socket , int $length [, int $flags = 0 [, string &$address ]] ) : string
The remote socket.
The number of bytes to receive from the socket.
The value of flags can be any combination of the following:
|STREAM_OOB||Process OOB (out-of-band) data.|
|STREAM_PEEK||Retrieve data from the socket, but do not consume the buffer. Subsequent calls to fread() or stream_socket_recvfrom() will see the same data.|
If address is provided it will be populated with the address of the remote socket.
Returns the read data, as a string
