PHP Warning: Call-time pass-by-reference has been
deprecated - argument passed by value; If you would
like to pass it by reference, modify the declaration of
socket_recv(). If you would like to enable call-time
pass-by-reference, you can set
allow_call_time_pass_reference to true in your INI
file. However, future versions may not support this
any longer. in
