Finding information about deprecated PHP functions?
<p>I am playing with the Yahoo Finance API using PHP, specifically session data and the like.</p>

<p>I am curious as to where I would look for information about deprecated features and/or functions. I want to use <code>session_register($var)</code> but I am running into errors (using WAMP).</p>

<p>EDIT: I have looked at php.net but I can't seem to find the appropriate information.</p>
