pfsockopen --  Open persistent Internet or Unix domain socket connection


int pfsockopen (string hostname, int port [, int errno [, string errstr [, int timeout]]])

This function behaves exactly as fsockopen() with the difference that the connection is not closed after the script finishes. It is the persistent version of fsockopen().
