Unexpected T_FUNCTION, but where?
<p>I've gotten my site to run perfectly on my local machine. However, migrating to production, I get roadblocked by "Unexpected T_FUNCTION ..." error.</p>

<p>I've stripped everything prior to the following code and still get the error reported for line 3. I just can't figure this out.</p>

<pre><code>&lt;?php
// Auth Check.
$authCheck = function() use ($app) {         &lt;---- Line 3
</code></pre>
