Description
string 
socket_read ( resource socket, int length [, int type] )
     The function socket_read() reads from the socket
     resource socket created by the
     socket_create() or 
     socket_accept() functions. The maximum number of bytes read
      is specified by the length parameter. Otherwise
      you can use \r, \n, or \0 to end reading 
      (depending on the type parameter, see below).
    
     socket_read() returns the data as a string on success, or 
     FALSE on error (including if the remote host has closed the
     connection). The error code can be retrieved with
     socket_last_error(). This code may be passed to
     socket_strerror() to get a textual representation of
     the error.
    
Note: 
      socket_read() returns a zero length string ("")
      when there is no more data to read.
     
     Optional type parameter is a named constant:
