Php obtains the domain name or host address echo $ _ SERVER [HTTP_HOST]. br. the webpage mainly obtains some information in the address bar, such as the domain name and port parameters.

The code is as follows:

Echo $ _ SERVER ['http _ host']."
";
// Obtain the webpage address
Echo $ _ SERVER ['php _ SELF ']."
";

If (! Empty ($ _ SERVER ["REQUEST_URI"])
{
$ ScrtName = $ _ SERVER ["REQUEST_URI"];
$ Nowurl = $ scrtName;
}

{
$ Nowurl = $ scrtName;
}
Else
{
$ Nowurl = $ scrtName ."? ". $ _ SERVER [" QUERY_STRING "];
}
}
Return $ nowurl;
}
// Instance call method
// Echo GEtCurUrl ();

Function getServerName ()
{
$ ServerName = strtolower ($ _ SERVER ['server _ name']? $ _ SERVER ['server _ name']: $ _ SERVER ['http _ host']);
If (strpos ($ ServerName, 'http ://'))
{
Return str_replace ('http: // ', '', $ ServerName );
}
Return $ ServerName;
}
// Instance call method
Echo getServerName ();

Echo 'http ://'. $ _ SERVER ['server _ name']. ':'. $ _ SERVER ["SERVER_PORT"]. $ _ SERVER ["REQUEST_URI"];

The pipeline code is as follows :? Php // Obtain the domain name or HOST address echo $ _ SERVER ['http _ host']. "br"; // Obtain the webpage location...
