Connecting to PostgreSQL can be achieved using various programming languages and libraries. Below is an example using PHP with the PDO extension to establish a connection to a PostgreSQL database.
<?php
$host = '127.0.0.1'; // PostgreSQL server host
$port = '5432'; // PostgreSQL server port
$dbname = 'your_database'; // Database name
$user = 'your_username'; // Database username
$password = 'your_password'; // Database password
try {
$dsn = "pgsql:host=$host;port=$port;dbname=$dbname;";
$pdo = new PDO($dsn, $user, $password);
// Set the PDO error mode to exception
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
echo "Connected successfully to PostgreSQL database.";
} catch (PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
?>
