# PHP HTTP Signaling (fallback for OVH shared hosting)

Endpoints (all accept GET or POST):
- join.php?room=ROOM&peer=ID -> returns {"ok":true,"peers":[...existing peer ids...]}
- send.php?room=ROOM&from=ID&payload=JSON -> queue a signaling payload (offer/answer/ice)
- poll.php?room=ROOM&peer=ID -> returns {"ok":true,"events":[{from, payload, ts}, ...]} and truncates queue for this peer

Notes:
- Storage is file-based in ./data/, TTL 5 minutes. No database.
- Use short polling (e.g. every 500–1000 ms) during negotiation; stop after DataChannel opens.
- This is ONLY for signaling. Media/data flows P2P via WebRTC.
