PHP：データベースから行をエコーするには？

Question

私はPHPとSQLにはかなり新しくなっています。私は自分のデータベースで作成したプロパティテーブルから行をエコーアウトする方法はありますか？

<?php 
    //CREATE CONNECTION 
    $servername = "localhost"; 
    $username = "root"; 
    $password = "root"; 
    $conn = new mysqli($servername, $username, $password); 
    // CHECK THE CONNECTION 
    if ($conn->connect_error) { 
     die("Connection failed: " . $conn->connect_error); 
    } 
    // CREATE ESTATE AGENTS DATABASE 
    $sql = "CREATE DATABASE IF NOT EXISTS estate_agents"; 
    if ($conn->query($sql) === TRUE) { 
     $dbname= "estate_agents"; 
     $newConnection = new mysqli($servername, $username, $password,$dbname); 
     //CREATE PROPERTIES TABLE 
     $sql = "CREATE TABLE IF NOT EXISTS properties (
      property_id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
      property_name VARCHAR(50) NOT NULL, 
      property_cost VARCHAR(50) NOT NULL, 
      property_description VARCHAR(500) NOT NULL 
     )"; 
     if ($newConnection->query($sql) === TRUE) { 
     } 
     else { 
      echo "Error creating table: " . $newConnection->error . "</br>"; 
     } 
    } 
    else { 
     echo "estate_agents not functional: " . $newConnection->error . "</br>"; 
    } 
?>
