Is !$page == false or $page in php?
<p>I saw the following code which uses if ($page!==false).
What are the differences if I use if ($page)?</p>

<pre><code>if($id){ // check that page exists
$page=dbRow("SELECT * FROM pages WHERE id=$id");
if($page!==false){
    $page_vars=json_decode($page['vars'],true);
    $edit=true;
}
</code></pre>

<p>Thanks in advance.</p>
