Connect:
$conStr = "pgsql:host=[host];port=5432;dbname=[db];user=[user];password=[password]";
$pdo = new \PDO($conStr);
$pdo->setAttribute(\PDO::ATTR_ERRMODE, \PDO::ERRMODE_EXCEPTION);

Insert:
$sql = 'INSERT INTO usertb(uname,pass) VALUES(:uname,:pass)';
$stmt = $pdo->prepare($sql);

// pass values to the statement
$stmt->bindValue(':uname', "hello");
$stmt->bindValue(':pass', "hello");

// execute the insert statement
$stmt->execute();

// return generated id
echo $pdo->lastInsertId();

Select:
$stmt = $pdo->query('SELECT uname, pass FROM usertb');
while ($row = $stmt->fetch(\PDO::FETCH_ASSOC))
    echo $row['uname'].",".$row['pass']."<br>";
