更改的属性值和文本标签

在我的论坛上，当上传图像时，它将获得以下 html：

<a target="_blank" href="attachment.php?aid=1" rel="nofollow">zebra.bmp</a>

为了使用我安装的插件，我需要匹配这些类型的 html 并将它们更改为：

<a href="attachment.php?aid=1" rel="fancyzoom">zebra.bmp</a>

在插件上它已经做了一些转换，例如：

$page=preg_replace('/\<a rel="nofollow" href="attachment.php\?aid=([0-9]+)" target="_blank"\>\<img/Usi','<a href="attachment.php?aid=$1" rel="fancyzoom"><img',$page);

现在我试图捕获我在问题开头发布的 html

$page=preg_replace('/\<a target="_blank" href="attachment.php\?aid=([0-9]+)" rel="nofollow"\>([a-zA-Z0-9_- ]+)\.(jpg|jpeg|gif|png|bmp|tif|tiff)\<\/a\>/Usi','<a href="attachment.php?aid=$1" rel="fancyzoom">$2.$3</a>',$page);

但上面的内容似乎不起作用，是因为 OR 括号吗？有没有办法在我只想要以上述图像扩展名结尾的文件的情况下进行此类替换？

原文

On my forum when an image is uploaded it will gain the follow html:

<a target="_blank" href="attachment.php?aid=1" rel="nofollow">zebra.bmp</a>

In order to use a plugin I have installed, I need to match those kind of html and change them to:

<a href="attachment.php?aid=1" rel="fancyzoom">zebra.bmp</a>

On the plugin it already does some conversion, example:

$page=preg_replace('/\<a rel="nofollow" href="attachment.php\?aid=([0-9]+)" target="_blank"\>\<img/Usi','<a href="attachment.php?aid=$1" rel="fancyzoom"><img',$page);

Now I am trying to catch the html I posted in the begin of my question

$page=preg_replace('/\<a target="_blank" href="attachment.php\?aid=([0-9]+)" rel="nofollow"\>([a-zA-Z0-9_- ]+)\.(jpg|jpeg|gif|png|bmp|tif|tiff)\<\/a\>/Usi','<a href="attachment.php?aid=$1" rel="fancyzoom">$2.$3</a>',$page);

But the above does not seem to work is it because of the OR parenthesis ?
Is there a way to make such replace where I just want the files ending with the above image extensions ?

您只需逃避减号：

$page=preg_replace('/\<a target="_blank" href="attachment.php\?aid=([0-9]+)" rel="nofollow"\>([a-zA-Z0-9_\- ]+)\.(jpg|jpeg|gif|png|bmp|tif|tiff)\<\/a\>',$page);

另请参阅我的演示。

=== 更新 ===

$page=preg_replace('/\<a.*?href="attachment.php\?aid=([0-9]+)".*?\>([a-zA-Z0-9_\- ]+)\.(jpg|jpeg|gif|png|bmp|tif|tiff)\<\/a\>/Usi','<a href="attachment.php?aid=$1" rel="fancyzoom">$2.$3</a>',$page);

我的新演示。

You only have to escape the minus:

$page=preg_replace('/\<a target="_blank" href="attachment.php\?aid=([0-9]+)" rel="nofollow"\>([a-zA-Z0-9_\- ]+)\.(jpg|jpeg|gif|png|bmp|tif|tiff)\<\/a\>',$page);

Also see my demo.

=== UPDATE ===

$page=preg_replace('/\<a.*?href="attachment.php\?aid=([0-9]+)".*?\>([a-zA-Z0-9_\- ]+)\.(jpg|jpeg|gif|png|bmp|tif|tiff)\<\/a\>/Usi','<a href="attachment.php?aid=$1" rel="fancyzoom">$2.$3</a>',$page);

My new demo.
