Symfony Yaml Component

Here to demo how to use Symfony Yaml Component to read Yaml file.

Install

composer require symfony/yaml

Parse Yaml file

#config.yaml
database:
    hostname: 'localhost'
    port:     3306
    name:     'db_name'
    username: 'db_username'
    password: 'db_secret_password'

serviceTopic:
    region: us-west-2
    topic: arn:aws:sns:us-west-2:12345678:production-good-service-topic

//test.php 
<?php

require "./vendor/autoload.php";

use Symfony\Component\Yaml\Yaml;

//$value will be an associate array
$value = Yaml::parseFile('./config.yaml');
var_dump($value);

//another way to parse file. $data and $value are identical
$data = \Symfony\Component\Yaml\Yaml::parse(file_get_contents( "./config.yaml"));
var_dump($data);

//after run: php test.php. Here is the result
array(2) {
  ["database"]=>
  array(5) {
    ["hostname"]=>
    string(9) "localhost"
    ["port"]=>
    int(3306)
    ["name"]=>
    string(7) "db_name"
    ["username"]=>
    string(11) "db_username"
    ["password"]=>
    string(18) "db_secret_password"
  }
  ["serviceTopic"]=>
  array(2) {
    ["region"]=>
    string(9) "us-west-2"
    ["topic"]=>
    string(60) "arn:aws:sns:us-west-2:12345678:production-good-service-topic"
