Leggere file TOML in PHP

In questo articolo vediamo come leggere un file TOML in PHP.

Per farlo useremo yosymfony/toml.

Per l'installazione possiamo usare composer:

composer require yosymfony/toml

Questo il file TOML:

title = "Test TOML"
version = "1.0.0"

[database]
host = "localhost"
port = 5432
username = "root"
password = "password"
databases = ["db_test"]
pool_size = 10
ssl_enabled = true

[server]
host = "0.0.0.0"
port = 8080
debug = false
allowed_hosts = ["*"]

[logging]
level = "INFO"
format = "%(asctime)s - %(levelname)s - %(message)s"
handlers = ["console", "file"]

[cache]
enabled = true
ttl = 3600
max_size = 1000

[features]
enable_api = true
rate_limit = 100

Qui sotto un pò di codice:

require_once 'vendor/autoload.php';

use Yosymfony\Toml\Toml;

try {
  $config = Toml::parseFile('test.toml');

  echo "Title: " . $config['title'] . "<br>";
  echo "Version: " . $config['version'] . "<br>";
  echo "Database Host: " . $config['database']['host'] . "<br>";
  echo "Database Port: " . $config['database']['port'] . "<br>";
  echo "Server Port: " . $config['server']['port'] . "<br>";
  echo "Cache Enabled: " . ($config['cache']['enabled'] ? 'true' : 'false') . "<br>";
  echo "Databases: " . implode(', ', $config['database']['databases']) . "<br>";

  echo "<br>--- Configurazione completa ---<br>";
  print_r($config);
  echo '<br>';

} catch (Exception $e) {
  echo "Errore nella lettura del file TOML: " . $e->getMessage() . "<br>";
}

function getConfig($config, $path, $default = null) {
  $keys = explode('.', $path);
  $value = $config;

  foreach ($keys as $key) {
    if (!isset($value[$key])) {
      return $default;
    }
    $value = $value[$key];
  }

  return $value;
}

echo "Log Level: " . getConfig($config, 'logging.level', 'DEBUG') . "<br>";
echo "Valore inesistente: " . getConfig($config, 'nonexistent.key', 'default_value') . "<br>";

Enjoy!
