title: Weird data stored in mysql db
body: <p>Can someone help me understand what data format this is and can the data from it be retrieved ?</p>
  
  <pre><code>a:2:{i:0;a:2:{i:0;i:1446681900;i:1;i:1446767700;}i:1;a:2:{i:0;i:1478304300;i:1;i:1478390100;}}
  </code></pre>
  
  <p>I know this is a very broad and probably off topic question but I found these record in my wp db and I'm not sure what they really mean or how to read them fully. What I was able to understand from them is that these are records for start and end date for calendar plugin. But still not 100% sure if I'm right or how I could turn this into readable data. </p>
