PHP：如何回显数据库中的行？

Question

我如何回应我在数据库中创建的属性表中的行？

<?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>";
    }
?>
