Use PHP to query domain name status whois class _ PHP Tutorial

Use PHP to query the domain name status whois class. Copy the code as follows :? ClassSearchDomain {var $ domain; functionSetDomain ($ udomain) {$ this-domain $ udomain;} get whois and analyze the domain name status. OK is not registered. it is not empty. The code is as follows:

Class SearchDomain
{
Var $ domain = "";
Function SetDomain ($ udomain)
{
$ This-> domain = $ udomain;
}
//
// Obtain whois and analyze the domain name status
// OK is not registered
// Non-null expiration time
// Null value unknown
//
Function GetInfo ()
{
/*
$ Dinfo = trim ($ this-> GetWhois ());
If ($ dinfo = "") return "";
If (eregi ("no match", $ dinfo) return "OK ";
// Return $ rs;
*/
$ Wl = "";
$ W_server = $ this-> GetServer ();
If ($ w_server = "") return "";
$ Fp = fsockopen ($ w_server, 43, $ errno, $ errstr, 30 );
If (! $ Fp)
{
Echo $ errstr;
Return "";
}
$ Out = $ this-> domain. "\ r \ n ";
$ Out. = "Connection: Close \ r \ n ";
Fputs ($ fp, $ out );
While (! Feof ($ fp ))
{
$ Wl = fgets ($ fp, 255 );
If (eregi ("no match", $ wl ))
{
Fclose ($ fp );
Return "OK ";
}
If (eregi ("Expiration Date", $ wl ))
{
$ Lines = split (":", $ wl );
$ T = trim ($ lines [1]);
$ Ts = split ("", $ t );
$ T = $ ts [0];
If (ereg ("[^ 0-]", $ t ))
{
$ Ts = split ("-", $ t );
$ T = $ ts [2]. "-". $ this-> MonthToNum ($ ts [1]). "-". $ ts [0];
}
Fclose ($ fp );
Return $ t;
}
}
Fclose ($ fp );
Return "";
}
//
// Obtain the whole whois information of the domain name

Function GetWhois ()
{
