How to enable “include credentials” in PHP curl request?

I have successfully executed fetch request from the javascript code below

await fetch("api-path", {
    method: "POST",
    headers: { "Content-Type": "application/json; charset=UTF-8" },
    body: JSON.stringify({ key01: "value01",  key02: "value02" }),
    credentials: "include"
})
.then (async (res) => {
    const jRes = await res.json();
    return jRes;
});

I want to make a similar request using php curl, however, not sure how to send credentials: “include” parameter with the php curl request ! Can some one guide for the same?

I have put the following code in PHP file, along with curl request, but it did not help:

header("Access-Control-Allow-Origin: *");
header('Access-Control-Allow-Credentials: true');
