Changed, thanks.
But you could set (int) instead using * 1.

There's a way to hide DP cvars.

Best way to detect if it's running DP is:

1- Send A2S_INFO
2- Check if you get 2 responses (one with new format and the second with an old format)
If you get 2 responses, then it's running DP

Also, if you get only 1 response:
- If it's the new format, then there's no DP, buy if the format is the old one, it's running DP and not allowing legit users to connect.

You don't need to do anything, PHP is a typeless language, it will accept it as an integer automatically based on the way you use it.

I'll inform myself about A2S_Info and will make changes if necessary, thanks.

Don't remember if HLTV uses the old protocol. Maybe you're right so my second point could cause false positives but can be controlled checking response contents.

[Black Rose]

I deleted it just seconds before your reply. Sorry.

But the contents of the packet is decided by the server, so how would that be any different? I'm definitely no expert, but I assuming that what the HLTV part means is that that's how it receives information from the server. But if so, all new servers would not be able to communicate with HLTV since they don't respond with packet header 0x6D. Or is it through a special request header perhaps that is unlisted or deprecated?

This should be sticky, so you don't have to search for it.

Server query code was moved from engine to steamclient one year ago, now it's handled there.

As far as I know:

- HLTV servers should answer with p48 responses
- HLTV clients should wait for p48 responses

I don't find any difference but I haven't tested how HLTV client work.

Check you're not using and old hltv client...

No, I don't use HLTV at all. Never did, never will. I just saw the comment in SourceQuery source code.

PHP Code:

        const S2A_INFO_OLD  = 0x6D; // Old GoldSource, HLTV uses it
// ...
            // Old GoldSource protocol, HLTV still uses it
            if( $Type == self :: S2A_INFO_OLD && $this->Socket->Engine == self :: GOLDSOURCE ) 


I guess it really doesn't matter. I see no reason why it would still be on p47 packets. So let's just assume it's not.
Thanks for your answers though.

I found several non-steam servers that only responds with the new header, but it is running dproto. If it is doing so successfully I don't know since so far all players in these servers have had a SteamID.
So why is that? Does it mean that dproto isn't working and it actually is a Steam-server? Or is there in fact cases where it non-steam is running on only p48, answering with the new header alone.
That would make A2S_INFO useless to determine Steam/Non-Steam.

You can also check the response to the request "\xFF\xFF\xFF\xFFgetchallenge steam\n".
Typical responses (with dproto):
