title: adding a static 1km grid to google maps using php
body: <p>I want to create a grid that I'll be overlaying google maps.
  The grid has to be static, meaning 1km² grid has to be exactly at the same location and has to be identifiable with a unique id.
  How can I achieve this in google maps and php?</p>
  
  <p>The best,

  <p>edit: Forgot to mention that I have to interact with these grids direclty, meaning changing color/style for each field.
  I've found some site that did it already <a href="https://ownthisworld.com/">https://ownthisworld.com/</a></p>
