title: Remove set of commas from mysql table
body: <p>There are a set of commas in each columns and rows. I want to eliminate the commas before and after string. </p>
  
  <p>eg: ,,,,,something, something,,,,,,,,,,,</p>
  
  <p>I want to eliminate only the commas and the front and end of the string, not the real comma in between. Its almost in every rows and columns. I know this can be done by regx and replace functions in php. </p>
  
  <p>But I want to make changes in the database itself. (New table without this unnecessary commas)</p>
