PHP is server side programming.
So you would generally use an App Access/Client Credentials token
Additionally you might want to consider EventSub instead of long polling the API
Then Twitch will tell you when your stream starts (and ends). Then store the data in your DB and do a call to your DB instead of a call to the API.
EventSub (webhook transport) also uses Client Credential tokens for this.
TLDR: No, it doesn’t change my answer.
