How to get token from aws.amazon.com in PHP?

Question

PHP

Hello!
Working with AWS Cognito
There are two options:

Client ID: zaq1xsw2cde3vfr4bgt5nhy6mju7
Pool ID: us-east-1_1qaz2wsx3edc

How to get the current token array in PHP (no need to refresh)?
I know that the response will be JSON in the format

{
   "AuthenticationResult": { 
     ...
      "IdToken": "string",
....
}

But here's how to get it using only cURL? Or do I need to install some libraries?
If it’s not difficult, then show a simple example, otherwise in Google there are only examples with a serious work of the service and you have to put a whole package of different classes there, and I just need to get one token knowing the two necessary parameters.
