title: change sqlite file size after "DELETE FROM table"
body: <p>I am working with sqlite3 file.</p>
  
  <p>First, I entered relatively big database, file size was about 100 mb.</p>
  
  <p>Than I made</p>
  
  <pre><code>$db-&gt;exec("DELETE FROM table");
  </code></pre>
  
  <p>and entered just a small part of that database. But file size remained 100 mb.</p>
  
  <p>What should you do to change sqlite file size when deleting it's content?</p>
