Lock script to the domain

[krugerauss]

I put this piece of code: if ( $_SERVER['HTTP_HOST'] != "ilmiodominio.com" ){ die(); } , I wanted to ask how can I add more than one domain, type: ilmiodominio.com and www.ilmiodominio.com, thank you.

I might just do something like this if you want to allow any sub-domain:

if( ! preg_match('/(^|\.)ilmiodominio\.com$/i', $_SERVER['HTTP_HOST'])) { 

If you want to restrict it to specific (or no) sub-domains:

if( ! preg_match('/^((sub1|sub2|sub3|www)\.)?ilmiodominio\.com$/i', $_SERVER['HTTP_HOST'])) { 

(Caveat, the above are untested, so typos are possible. )

alternatively:

// set an array of allowed hosts.
$allowed = array("ilmiodominio.com", "www.ilmiodominio.com", "www2.ilmiodominio.com", "sub.ilmiodominio.com");

// if the current host is not in the array, then kill it.
if ( !in_array($_SERVER['HTTP_HOST'], $allowed) === TRUE ){ die(); }
