How to fix error with php + docker?

Question

PHP

I am running a yii2 project in docker. The problem is that when opening any external resource, through fopen, curl and so on, I catch the error:

fopen(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution docker-compose

version: '3.5'
services:
  nginx:
    container_name: ${COMPOSE_PROJECT_NAME}_nginx
    image: nginx:latest
    restart: always
    ports:
      - "${NGINX_PORT}:80"
      - "${NGINX_PORT_SSL}:443"
    volumes:
      - ./docker/nginx/${NGINX_HOST}.conf:/etc/nginx/conf.d/default.conf
      - .:/var/www/${COMPOSE_PROJECT_NAME}
    links:
      - php
  php:
    container_name: ${COMPOSE_PROJECT_NAME}_php
    build: ./docker/php
    restart: always
    volumes:
