Extraction #row#99#col#fenpeixishu.gif#row# of 91#col# and #row#97#col#jiaotilizi.gif#row#98#col# in chemical dosage

Structure is like this: ID + #col # + name + #row #
91#col# in the dosage and #row# 97#col#jiaotilizi.gif#row#

A lot of this data to dispose of GIF

PHP Code

  
   $contents = Preg_replace ('/[\w] #col # (. *?). gif#row# '/I, ', $contents);

I would like to replace it with empty, is this method not very good?
And this is a mistake.
