MYSQL和PHP新闻系统[关闭]

Question

I have this news system but I can't figure out how to do it like this: news.php?id=1 then it will output the news id 1. Please help.

I have this so far:

<?php
include_once('includes/config.php');
if($id != "") {
    $id = mysql_real_escape_string($id);
    $sql = mysql_query("SELECT * FROM news WHERE id = '$id'");
}
$res = mysql_query($sql);
while($row = mysql_fetch_assoc($res)){
if(isset($_GET['id']));
    echo $res['body'];
}
?>

It connects to the database (details are stored in the config).

Answer 1

the parameters after the ? in the URL are GET items. Use this:

<?php

if (isset($_GET['id'])) {

    $id = $_GET['id'];
    // Rest of your code

}
