$ Now = getdate ();
$ Storetime = $ now ["weekday"]. "". $ now ["month"]. "". $ now ["year"];
$ Storetime. = "time :";
If ($ now ["hours"] <10 ){
$ Storetime. = "0". $ now ["hours"];
} Else {
$ Storetime. = $ now ["hours"];
}

$ Storetime. = ":";
If ($ now ["minutes"] <10 ){

$ Storetime. = ":";
If ($ now ["seconds"] <10 ){
$ Storetime. = "0". $ now ["seconds"];
} Else {
$ Storetime. = $ now ["seconds"];
}
If (isset ($ data )){
$ Counter = ++ $ data [l];
Setcookie ("data [0]", $ storetime, time () + (60*60*24 ));
Setcookie ("data [l]", $ counter, time () + (60*60*24); setcookie ("data [2]", $ username, time () + (60*60*24 ));
Echo "<B> <center> hi". $ data [2]. "! ! </Center> </B> <br> n ";

} Else {
If (isset ($ username) & isset ($ password )){
If ($ password = "superpass "){
$ Counter = 0;
Setcookie ("data [0]", $ storetime, time () + (60*60*24 ));
Setcookie ("data [l]", $ counter, time () + (60*60*24 ));
