Deleting all files from a folder when view pages

Question

当查看页面或没有任何单击按钮时，如何实现自动删除文件夹中的所有文件，例如有人访问页面index.php，然后自动执行删除文件夹中的所有文件？

Answer 1

Try this code

$iterator = new FilesystemIterator($dir);
    while($iterator->valid()) {
           @unlink($dir.$filename);
    }

Answer 2

$(function() {
$i=0;
$handle = opendir($dir); 
while ($filename = readdir($handle))
{ 
   if($filename!="."&&$filename!="..")
   {
       if(!is_dir($dir.$filename))
       {
          @unlink($dir.$filename);
       }
       else
       del_cache($dir.$filename."/");
  }
}
});

It is called when the page is loaded. There is no need to call function.
