$ Host = $ _ POST [hostname];

$ Dbname = $ _ POST [dbname];
$ Siteurl = "http: //". $ _ POST [siteurl];
$ Sitekeyword =$ _ POST [sitekeyword];
$ Sitedescription = $ _ POST [sitedescription];
$ Sitename = $ _ POST [sitename];

$ Fp = fopen ("./include/config. func. php", "w + ");
If (flock ($ fp, LOCK_EX ))
{
Fwrite ($ fp, "<"."? Php \ r \ n ");
Fwrite ($ fp, "\ $ host = \" $ host \ "; \ r \ n ");
Fwrite ($ fp, "\ $ user = \" $ user \ "; \ r \ n ");
Fwrite ($ fp, "\ $ passwd = \" $ passwd \ "; \ r \ n ");

Fwrite ($ fp, "\ $ sitekeyword = \" $ sitekeyword \ "; \ r \ n ");
Fwrite ($ fp, "\ $ sitedescription = \" $ sitedescription \ "; \ r \ n ");
$ Tmp = "\ $ conn = mysql_connect (\ $ host, \ $ user, \ $ passwd) or die (mysql_error (); \ r \ n ";
