    Just to let you know that I modified your function to check if the file date is within a given date interval:

    
    public function doFileDatesComparison($file) {
    	   if (is_file($file)) {
    		   $filePath = $file;
    		   if (!realpath($filePath)) {
    			   $filePath = $_SERVER["DOCUMENT_ROOT"] . $filePath;
    		   }
    		   $fileDate = filemtime($filePath);
    		   if ($fileDate) {
    			   $fileDate = date('U', $fileDate);
    
    			   if ($fileDate > $this->downBound && $fileDate upBound) {
    			   		return date('Y/m/d H:i:s', $fileDate);
    			   }
    		   }
    			return false;
    	   }
    	   return false;
    	}

      Whops my fault, I’m posting the method again after turning < into <

      
      public function doFileDatesComparison($file) {
      	   if (is_file($file)) {
      		   $filePath = $file;
      		   if (!realpath($filePath)) {
      			   $filePath = $_SERVER["DOCUMENT_ROOT"] . $filePath;
      		   }
      		   $fileDate = filemtime($filePath);
      		   if ($fileDate) {
      			   $fileDate = date('U', $fileDate);
      
      			   if ($fileDate > $this->downBound && $fileDate < $this->upBound) {
      			   		return date('Y/m/d H:i:s', $fileDate);
      			   }
      		   }
      			return false;
      	   }
      	   return false;
      	}
