title: Remove Image background with php and save transparent png
body: <p>I want to remove the white background of any image uploaded on the site working on PHP platform. The uploading function is done but messed up with this functionality. </p>
  
  <p>Here is the link I found here:
  <a href="https://stackoverflow.com/questions/8041703/remove-white-background-from-an-image-and-make-it-transparent">Remove white background from an image and make it transparent</a></p>
  
  <p>But this is doing reverse. I want to remove the colored background and make it image with transparent background.</p>
