need help in PHP

<?php
// This is to check if the request is coming from a specific domain
$ref = $_SERVER['HTTP_REFERER'];
$refData = parse_url($ref);

if($refData['host'] !== 'domain') {
// Output string and stop execution
die("Hotlinking not permitted");
}

echo "Executing code here";
?>

Please tell how to add multiple domains in this execution

I also tried- if($refData['host'] != 'website1.com' || $refData['host'] != 'website2.com') {

From your code ...

<?php
// This is to check if the request is coming from a specific domain 
$ref = $_SERVER['HTTP_REFERER'];
$refData = parse_url($ref);

if($refData['host'] !== 'domain') {
  // Output string and stop execution
  die("Hotlinking not permitted");
}

echo "Executing code here";

Q. When you use the OR condition in the if can you share a screenshot of the error?

Also you could put the options in an array to allow it to be scalable and cleaner, for example

in_array ( mixed $needle , array $haystack , bool $strict = false ) : bool

From the php docs

if (in_array($refData['host'], [ 'domain1', 'domain2', 'domain3' ])) {

[Mackie22w]

actually, this was the real code I was trying to use

<?php
// This is to check if the request is coming from a specific domain
$ref = $_SERVER['HTTP_REFERER'];
$refData = parse_url($ref);

if($refData['host'] !== 'ecopeak.net') {
  // Output string and stop execution
  die("<meta http-equiv='refresh' content='1;url=http://slayygames.com/' /> Not Allowed.");
}

?>

but when I try to put other code (Multiple domains) it doesn't work

this code work when I use single domain

I think @eddiejaoude has answered your question here @Mackie22w but if you look at his example

if (in_array($refData['host'], [ 'domain1', 'domain2', 'domain3' ])) {

what you actually want is the opposite of in_array being true (e.g. you want to whitelist domains that can use this)

try this:

if (!in_array($refData['host'], [ 'domain1', 'domain2', 'domain3' ])) {
  // Output string and stop execution
  die("<meta http-equiv='refresh' content='1;url=http://slayygames.com/' /> Not Allowed.");
}
