title: Minimum for varchar?
body: <p>I thought you could set varchar as varchar(min,max), but I must have mistaken. What's the syntax to set a min and max? Or do I have to use PHP to do that? </p>
  
  <p><strong>Update:</strong>
  Let me add more context. I'm making a field for usernames, so I thought I could set the minimum and maximum for varchar in MySQL. Seems I can only set the length which is 0 to 255. I'm guessing this means I have to use PHP to add the minimum restriction</p>
