title: what's the point of serializing arrays to store them in the db?
body: <p>I see that people store arrays as like:</p>
  
  <p><code>a:6:{i:0;s:5:"11148";i:1;s:5:"11149";i:2;s:5:"11150";i:3;s:5:"11153";i:4;s:5:"11152";i:5;s:5:"11160";}</code></p>
  
  <p>why can't they just be:</p>
  
  <p><code>11148,11149,11150,11153...</code></p>
  
  <p>and have sql "Type" be "Array" ?</p>
  
  <p>this way it's shorter and you can change the values directly in the databse without having to alter "s:" or "i:".</p>
