title: issue with export and import zipped sql file in phpmyadmin
body: <p>I am trying to export a database from server A, and then import it to server B, the sql file is too large, so I want to zip it, for export, there is one option called compression, on the select-list, there are 3 items:zipped, gzipped, bzipped, </p>
  
  <p>Question:</p>
  
  <p>1.what is the different between zipped, gzipped, bzipped? which one should I choose?</p>
  
  <p>2.when I import it to server B, can I just upload the zip file? is there anything i need to do before import or after import?</p>
