我在用百度的ueditor进行文章编辑时会上传图片到服务器，做删除文章这一功能的时候想了一下怎么样把文章中的图片也删除掉，下面就是我的做法，权当做一个笔记，代码写的很差，毕竟是新手，欢迎高人指点$article = M('Article');<br>
$content = $article->where('id="'.$_GET['id'].'"')->getField('content');<br>
$img_arr = array();<br>
//$regex = '/img src="\/(.*?)"/i';//只删除本地图片<br>
$regex = '/img\s+src=['\"]\/{1}(.*?)['\"]/';<br>
preg_match_all($regex,$content,$img_arr);<br>
$img_arr = $img_arr[1];<br>
for($i=0;$i<sizeof></sizeof>
if(!unlink('./'.$img_arr[$i])){<br>
die('删除文章中的图片失败！');<br>
}<br>
}
