我的PHP新手，这是修订后的问题。我也问过这个问题，在许多论坛，但是，我根本就不能得到什么错误。

I am PHP newbie and this is revised question. I have asked this question, in many forum but, I simply can't get what is going wrong.

其目的就是要改变这个URL从

The purpose is just to change this url from

的http：//localhost/DIRECTORY/AID/news.php A_ID = 24 到 的http：//本地主机/目录/ AID /新闻/ this_is_article_title

对于这一点，我有三排 id``title``content 所以，在这个例子中我试图呼应我们的行（ID）24号：   ID = 24 标题=这是文章的标题 内容=这是内容

For this, I have three rows id``title``content so, for this example I am trying to echo our row (id) number 24 : id=24 title=This is article title content=this is content

好了，希望是显而易见的。现在，让我们去的URL。

Ok, hope that was clear. Now, lets to go the URL.

的http：//本地主机是好..本地主机（我已经安装了XAMPP）

http://localhost is well.. localhost (I have XAMPP installed)

目录/ 是保存在我把我的网站项目的其他文件夹中的文件夹。

DIRECTORY/ is a folder that holds other folders in which I put my site projects.

AID / 名为决赛的现场项目根文件夹。它是在目录/ 文件夹中找到，这个文件夹里面有文件，如：

AID/ a root folder for the site project called FINAL. it is found inside the DIRECTORY/ folder, and inside this folder there file such as:

的.htaccess 的index.php news.php /图像 / CSS / JS

在的.htaccess 我有这个code

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
^news/([A_Za_z0_9_]+)$ DIRECTORY/AID/news.php?id=$1 [QSA,L]

希望，一切都清楚了为止。 现在，在指数PHP的，我有这样的功能，即获得所有新闻标题和内容数据库，并创建一个链接的 news.php 的含义，当你点击一个从索引页标题，它把你带到 news.php？ID = 24 。下面是函数：

Hope, everything is clear so far. Now in the index php, I have this function, that gets all news title, and content from database and creates a link for the news.php meaning, when you click on a title from the index page, it takes you to news.php?id=24. Here is the function:

function news_preview() {
$query = "SELECT * FROM news ORDER BY id DESC LIMIT 5  ";
$result = mysql_query($query) or die(mysql_error());
while($row=mysql_fetch_array($result)) 
{   echo "<a href="news.php?news=$row[id]">  ". substr($row['title'], 0,26)."...</a><br/>".; }
}

如果你看到上面清楚了，我送行的ID，以news.php在这条线。

If you see the above clearly, I am sending id of row to news.php with in this line.

回声＆LT; A HREF = news.php新闻= $行[ID] ？＆gt;中。 SUBSTR（$行['标题']，0,26）＆LT; / A＆GT;

现在，在news.php里面没有太多的事，我只是得到了ID和呼应的结果。但是，我需要的URL更改为我做的。而且，我不知道是什么问题。

Now, inside the news.php there is not much to do, I just get the id and echo the result. But, i need the url to change as I do. And, I don't know what the problem is.

推荐答案

首先，您需要更改HTML的HREF，给新的URL格式

First of all, you would need to change the href in the html, to give the new url format

function news_preview() {
$query = "SELECT * FROM news ORDER BY id DESC LIMIT 5  ";
$result = mysql_query($query) or die(mysql_error());
while($row=mysql_fetch_array($result)) 
{   
  echo "<a href="/news/$row[id]">  ". substr($row['title'], 0,26)."...</a><br/>".; }
}

喜欢 HTTP的将生成的URL：//本地主机/新闻/ 24

请注意，我删除了 /目录/ AID 从URL，如htaccess的建议，你想要的是URL，而不是你的文字说明。

Note that I removed the /DIRECTORY/AID from the url, as the htaccess suggest you want that to be url, as opposed to what you stated in the text.

但是，现在得到了的http：//本地主机/新闻/ this_is_article_title 类型的URL。因为有之间 this_is_article_title 不相关的标识 24 ，实现这一目标的唯一途径是通过添加标识该网址也还是有PHP查找与这个称号在数据库中的新闻文章。

But now the get to the http://localhost/news/this_is_article_title type of url. Because there is no correlation between this_is_article_title and the id 24, the only way to achieve this is by either adding the id to the url too, or to have the php lookup the news-article with this title in the database.

这最后的解决方案，但也存在一些问题，因为你不能只是我们的一个url称号。你必须转义字符。同时你必须添加一个索引在数据库中的标题行获得更好的性能。

This last solution however has some problems, as the you can't just us the title in a url. You have to escape characters. Also you'll have to add a index for the title row in the DB for better performance.

所以我会去的第一个解决方案。我们会产生这样的网址

So I'll go with the first solution. We will generate urls like this

的http：//本地主机/新闻/ 24 / this_is_article_title

首先PHP的一部分

function news_preview() {
$query = "SELECT * FROM news ORDER BY id DESC LIMIT 5  ";
$result = mysql_query($query) or die(mysql_error());
while($row=mysql_fetch_array($result)) 
{ 
  $url = "/news/$row[id]/".preg_replace('/[^a-zA-Z0-9-_]/', '_', $row['title']);  
  echo "<a href="$url">  ". substr($row['title'], 0,26)."...</a><br/>".; }
}

接下来是htaccess的部分。

Next comes the htaccess part.

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^news/([0-9]+)/([A-Za-z0-9_-]+)$ DIRECTORY/AID/news.php?id=$1 [QSA,L]

这应该这样做，我认为。

That should do it I think.
