title: Upgrade PHP 7.2 to 7.3 on Mac Mojave
body: <p>I would like to upgrade my PHP from 7.2 to 7.3 on my Mac Mojave.</p>
  <p>My current version is 7.2.25 (when I execute <code>php -v</code>).</p>
  <p>I did that:</p>
  <pre><code>brew install php@7.3
  </code></pre>
  <p>It seems that it installed some things. But <code>php -v</code> still displays 7.2.25.</p>
  <p>I restarted my computer, and still get the same. What more can I do?</p>
