Not much nonsense. Directly run the Code:
Sock_post.php:

The Code is as follows:

Function sock_post ($ url, $ data = ''){
$ Url = parse_url ($ url );
$ Url ['scheme '] | $ url ['scheme'] = 'http ';
$ Url ['host'] | $ url ['host'] = $ _ SERVER ['HTTP _ host'];
$ Url ['path'] [0]! = '/' & $ Url ['path'] = '/'. $ url ['path'];

$ Query = $ data;
If (is_array ($ data) $ query = http_build_query ($ data );

$ Fp = @ fsockopen ($ url ['host'], $ url ['Port']? $ Url ['Port']: 80 );
If (! $ Fp) return "Failed to open socket to $ url [host]";

Fputs ($ fp, sprintf ("POST % s HTTP/1.0/n", $ url ['path'], $ url ['query']? "? ":" ", $ Url ['query']);
Fputs ($ fp, "Host: $ url [host]/n ");
Fputs ($ fp, "Content-type: application/x-www-form-urlencoded/n ");
Fputs ($ fp, "Content-length:". strlen ($ query). "/n ");
Fputs ($ fp, "Connection: close/n ");

Fputs ($ fp, "$ query/n ");

$ Line = fgets ($ fp, 1024 );

If (@! Eregi ("^ HTTP/1/.. 200", $ line) return;

$ Results = "";
$ Inheader = 1;
While (! Feof ($ fp )){
$ Line = fgets ($ fp, 1024 );
If ($ inheader & ($ line = "/n" | $ line = "/r/n ")){
$ Inheader = 0;
} Elseif (! $ Inheader ){
$ Results. = $ line;
}
}
Fclose ($ fp );

Return $ results;
}
$ Re = sock_post ('HTTP: // localhost/direct_post/get_post.php? Id = 1', array ('wel' => 'hello '));
Echo $ re;
?>

Get_post.php:

The Code is as follows:

Echo "post :";
Print_r ($ _ POST );
Echo 'get :';
Print_r ($ _ GET );
?>
