Dont output directory's hidden files of my PC

PHP
1

Hello …I just was trying to output the file names of different folders in my PC using PHP code…But I found that it outputs actually more than visible files in that particular folder…So what did I mean by visible that when I count the number of files in my folder it appears 18 but when i output it appears that the numer is 20. That two files are not visible. One if the is “Folder.jpg” and the second of them is a “.doc” file i opened and think it is inserted by “Administrator”…This is the code

<?php

 function getDirectoryList ($directory)  
  { 

	// create an array to hold directory list 
	$results = array(); 

	// create a handler for the directory 
	$handler = opendir($directory); 

	// open directory and walk through the filenames 
	while ($file = readdir($handler)) { 

	  // if file isn't this directory or its parent, add it to the results 
	  if ($file != "." && $file != "..") { 
		$results[] = $file; 
	  } 

	} 

	// tidy up: close the handler 
	closedir($handler); 

	// done! 
  return $results; 

  } 
  $array_1=getDirectoryList("C:\\Documents and Settings\\&#1040;&#1076;&#1084;&#1080;&#1085;&#1080;&#1089;&#1090;&#1088;&#1072;&#1090;&#1086;&#1088;\\&#1052;&#1086;&#1080; &#1076;&#1086;&#1082;&#1091;&#1084;&#1077;&#1085;&#1090;&#1099;\\Downloads"); 

  
 foreach($array_1 as $value) 
 { 
 echo "<br/>".$value; 
 }
?>

So here is my question …how can I output only that 18 files and not that invisible files ? Since I want to work only with files that I see.

Please be gentle and help me.

You could use FilterIterator and DirectoryIterator here, let’s say your filter is call HiddenFileFilter, this would be the code you need to loop through the directory.


$directory = new DirectoryIterator('/');
foreach(new HiddenFileFilter($directory) as $file){
  echo $file->getFilename(), PHP_EOL ;
}

The code that filters out hidden files would look something similar to


class HiddenFileFilter extends FilterIterator
{
  public function accept(){
    return ! $this->isCurrentFileHidden();
  }
  
  protected function isCurrentFileHidden(){
    
    $path = $this->getCurrentFullFilePath();
    
    if($this->isRunningOnWindows()){
      return $this->isFileHiddenOnWindows($path);
    }
    
    return $this->isFileHiddenOnUnix($path);
  }
  
  protected function isRunningOnWindows(){
    return strtoupper(substr(PHP_OS, 0, 3)) === 'WIN';
  }

  protected function getCurrentFullFilePath(){
    $file = $this->current();
    return $file->getPathname() . DIRECTORY_SEPARATOR . $file->getFilename();
  }

  protected function isFileHiddenOnUnix($path){
    # execute bash to determine file is hidden
    return true;
  }

  protected function isFileHiddenOnWindows($path){
    # execute cmd to determine file is hidden
    return true;
  }
}

The HiddenFileFilter::accept() method should return either true or false; true to display the file and false if not.

I did spot this over at the manual though, it might be of interest.

<?php
class HiddenFileFilter extends FilterIterator
{
  public function accept(){
    return ! $this->isCurrentFileHidden();
  }

  protected function isCurrentFileHidden(){

    $path = $this->current()->getPathname();

    if($this->isRunningOnWindows()){
      return $this->isFileHiddenOnWindows($path);
    }

    return $this->isFileHiddenOnUnix($path);
  }

  protected function isRunningOnWindows(){
    return strtoupper(substr(PHP_OS, 0, 3)) === 'WIN';
  }

  protected function isFileHiddenOnUnix($path){
    # execute bash to determine file is hidden
    return true;
  }

  protected function isFileHiddenOnWindows($path){
    $output = exec(sprintf('attrib "%s"', escapeshellarg($path)));
    return 'H' === substr($output, 4, 1);
  }
}

HiddenFileFilter::isFileHiddenOnWindows works now. :slight_smile:
