Docker php curl connection refused

[demonstration below]

Greeting developers! Recently I'm trying to dockerize a php website, but I got connection refused when trying to curl from one to another.

Basically I have three site:

The problem is connection is refused when I try to call api from first-site.

./docker-compose.yml

version: "3.1"
services:
  www:
    build: ./www/.
    ports:
      - "0.0.0.0:8080:80"
      - "0.0.0.0:443:443"
    volumes:
      - ./htdocs:/var/www
      - ./www/conf:/etc/httpd/conf
    networks:
      - local

  php:
    build: ./php/.
    ports:
      - '9000'
    volumes:
      - ./htdocs:/var/www
    networks:
      - local

networks:
  local:
    driver: bridge

        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);
}
?>

when I execute this code I got

Fatal error: Curl failed with error #56: Proxy CONNECT aborted in /var/www/api/xxxxxp on line xx

My own assumption was, the php and www container I am having in docker-compose.yml are not connected or linked on the same network, but I cannot figure out the solution until now. Please help!!!! I appreciate that <3

The names of your services are networkable. For instance, I can put mariadb in my database connections instead of localhost or an ip. In the example below, awesome.scot is my Apache server, you'll notice another called app, that literally just mounts the files, so it's possible to add a service for each web site! And if you refer to the service names, your calls will complete without any problems :-)

Here's the Docker compose file for my LAMP sdtack. If you'd like to try it or steal bits from it, you'll find it here https://github.com/delboy1978uk/lamp, It comes with mailhog as well, self signed ssl, xdebug, etc.

version: '2'

volumes:
    db_data:
        driver: local

services:
    awesome.scot:
        build: ./build/httpd
        links:
            - php
        ports:
            - 80:80
            - 443:443
        volumes_from:
            - app

    php:
        build: ./build/php
        ports:
            - 9000
            - 9001
        volumes_from:
            - app
        links:
            - mariadb
            - mail
        environment:
            APPLICATION_ENV: 'development'
        user: php:staff

    app:
        image: httpd:2.4.38
        volumes:
            - ./:/var/www/html
        command: "echo true"

    mariadb:
        image: mariadb:latest
        volumes:
            - ./build/data:/docker-entrypoint-initdb.d
            - db_data:/var/lib/mysql
        environment:
            MYSQL_ROOT_PASSWORD: '[123456]'
            MYSQL_USER: dbuser
            MYSQL_PASSWORD: '[123456]'
        ports:
            - 3306:3306

    mail:
        image: mailhog/mailhog
        ports:
            - 1025:1025
            - 8025:8025
