从 SQL 数据库添加网站内容

我对PHP很陌生，所以这对某些人来说可能是一个愚蠢的问题，但我的网站目前被分解为包含，我已经设法建立了数据库连接，但我希望"关于"页面中的内容来自SQL数据库，而不是静态HTML。我的问题是我实际上如何编写 PHP 以从数据库中获取内容并将其显示在相关标签中？

这是该网站的链接：http://midway-media.net/3/about.php

这是我目前的代码：

<?php include_once "includes/scripts.php"; ?>
<?php include_once "includes/header.php";?> 
<?php
    $db_host = "localhost";
    $db_user = "root";
    $db_pass = "";
    $db_name = "camelhorse";
    $db_error_one= "<h1>Could not connect to database</h1>";
    $db_error_two= "<h1>Database 'camelhorse' is not available</h1>";
    @mysql_connect ($db_host,$db_user,$db_pass) or die ($db_error_one);
    @mysql_select_db("$db_name") or die ("$db_error_two");
?>
