PHP uses the built-in Dir class to implement directory traversal removal, Phpdir

The example in this article describes how PHP uses the built-in Dir class to implement directory traversal removal. Share to everyone for your reference. The implementation method is as follows:

function Cleardir ($dir) {if (file_exists ($dir)) {  if (!is_dir ($dir))   exit ("{$dir} is not a directory");  else  {   $dirObj = dir ($dir);   while ($file = $DIROBJ->read ())   {    if (Is_dir ($dir. ') /'. $file) && $file!== '. ' && $file!== ' ... ')    {     Cleardir ($dir. ') /'. $file);     if (@!rmdir ($dir. ' /'. $file))       
";    }    ElseIf ($file!== ' && $file!== ' ... ')    {     if (unlink ($dir. ') /'. $file))       echo "{$file} file successfully deleted
";    }   }  } } else  exit ("{$dir} does not exist");} Cleardir ('./demo ');

I hope this article is helpful to everyone's PHP programming.
