My Layout:
<?php
// <meta>
$this->headMeta()
->appendHttpEquiv('Content-Type', 'text/html; charset=UTF-8')
->appendHttpEquiv('Content-Language', 'en-US');
$this->headTitle()
->headTitle('My Page', 'APPEND');
echo $this->doctype('XHTML1_STRICT');
?>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<?= $this->headMeta() ?>
<?= $this->headTitle() ?>
</head>
<body>
<?= $this->layout()->content ?>
</body>
</html>
My View:
<h1>HELLO WORLD</h1>
In the course of debugging this, I've tried to take out all of the
possible bugs, I've narrowed it down to one thing: attempting to
json_decode a perfectly valid JSON string, which I've attached, prior
to preDispatch(), View, Layout rendering causes blank screen.
