php清空(删除)指定目录下的文件,不删除目录文件夹的方法
web 开发中我们可能会碰到需要将某个目录下的所有文件清空,但不删除这个目录下的子目录(当然也不会删除被删除的根目录)的情况。
那么对于这种只删除文件而不删除目录的方法,你是如何处理的呢?
下面博主将要和你分享一下对于这个问题的一种比较好的解决办法。
看下面这个函数:
<p>/*删除指定目录下的文件,不删除目录文件夹*/</p>function delFile($dirName){<br /> if(file_exists($dirName) && $handle=opendir($dirName)){<br /> while(false!==($item = readdir($handle))){<br /> if($item!= "." && $item != ".."){<br /> if(file_exists($dirName.'/'.$item) && is_dir($dirName.'/'.$item)){<br /> delFile($dirName.'/'.$item);<br /> }else{<br /> if(unlink($dirName.'/'.$item)){<br /> return true;<br /> }<br /> }<br /> }<br /> }<br /> closedir( $handle);<br /> }<br />}
