Duplicate Files Deletor class

[imported_ksg91]

I recently had many photos duplicated and I was lazy to select each duplicate photo and then delete, so I wrote a small php class to do the job.
You need to instantiate the class with directory that contain duplicate files and the pattern that is unique to duplicate file.

WARNING: Be careful with duplicate file's pattern if you do not wish to delete important files.

<?php 
/**

 *This simple class deletes files that has specific sub string in its file name. 
 *I used it to delete duplicate photos.  
 *You may edit it as per your need.  
 * 
 *WARNING: Be careful while choosing pattern for duplicate files.  
 *         If the pattern you choose is not unique to duplicates, you will 
 *         lose unique and important files.

class DuplicateDelete 
{ 
  private $dir,$handle,$dupPattern,$currentFile; 
  /*constructor to set directory in which files are to be searched and subsring  
   that a duplicate file will contain. */ 
  function __construct($dir,$dupPattern) 
  { 
    $this->dir=$dir; 
    $this->handle=opendir($dir); 
    $this->dupPattern=$dupPattern; 
  } 
  /*This function will delete all duplicate files*/ 
  function deleteDuplicates() 
  { 
    while (false !== ($this->currentFile = readdir($this->handle))) { 
        if($this->isDuplicate()){ 
          unlink($this->dir."\\".$this->currentFile); 
          //echo $this->currentFile."
"; 
        } 
    } 
  } 
  /*This function will check if currentFile is duplicate. Returns true if  
    duplicate, else false. */  
  function isDuplicate() 
  { 
    if(strstr($this->currentFile,$this->dupPattern)) 
      return true; 
    else  
      return false; 
  } 
} 

/* EXAMPLE */ 

/* I had photos and videos that were somehow duplicated and all duplicate photos/videos 
  contained _2 at the end of file. So the substring for those duplicate photos/videos 
  would be "_2." */ 
$dd=new DuplicateDelete("E:\\Robo-Opus 11\\New folder\\New folder","_2.");  
$dd->deleteDuplicates(); 
?>
