<h2 class="title">Deprecated features in PHP 5.3.x</h2>
<p class="simpara">
PHP 5.3.0 introduces two new error levels: <strong><code>E_DEPRECATED</code></strong>
and <strong><code>E_USER_DEPRECATED</code></strong>. The
<strong><code>E_DEPRECATED</code></strong> error level is used to indicate that a
function or feature has been deprecated. The
<strong><code>E_USER_DEPRECATED</code></strong> level is intended for indicating
deprecated features in user code, similarly to the
<strong><code>E_USER_ERROR</code></strong> and <strong><code>E_USER_WARNING</code></strong>
levels.
</p>
<p class="simpara">
The following is a list of deprecated INI directives. Use of any of these INI
directives will cause an <strong><code>E_DEPRECATED</code></strong> error to be thrown
at startup.
