I have been wondering about the second parameter of the unlink command.
When I use the unlink command, I always use the realpath of the file location.
What exactly does the second parameter do and should I be using it ?
This is how I currently use it:
// DELETE FILES 
   $folder_path = '';
   $files = '';
   
   $folder_path = $_SESSION['TmpWorkPdfsToUpload'];
   $files = glob($folder_path . '/*');  
   foreach($files as $file)
    { 
     if (is_file($file))
      { 
          try 
         {
           
         $strRealLocation = realpath($file);
         chmod($strRealLocation,0777);
         unlink($strRealLocation);
          echo '<BR>DELETED FILE: ' . $strRealLocation . PHP_EOL;
      
          }catch(Exception $e){
            echo 'Message: ' . $e->getMessage() . PHP_EOL;
         }
      }else{
         echo '<BR>NO FILES TO DELETE';
       }
    }
Thank you in advance.
