title: PHP MYSQL UPDATE WHERE multiple conditions
body: <p>I was wondering if you can do an Update with multiple conditions like so:</p>
  
  <pre><code>UPDATE participantes SET confirmado = 1 WHERE id = 19 AND id = 20 AND id = 21;
  </code></pre>
  
  <p>participantes -> Table</p>
  
  <p>confirmado -> field of the table participantes.</p>
