title: Query string (with space in between) in php html
body: <p>I am trying to do a query string in html.
  String that I want to pass is "Book Cover".
  But I only managed to get Book.
  How should I go about doing it?</p>
  
  <p>Below is my code:</p>
  
  <pre><code>    &lt;a href=book.php?category=Book Cover&gt;Book Cover&lt;/a&gt;
  </code></pre>
