-<p>This function runs a <tt class="docutils literal"><span class="pre">function_exists()</span></tt> check and if the
-<cite>Suhosin extension &lt;http://www.hardened-php.net/suhosin/&gt;</cite> is loaded,
-checks if it doesn&#8217;t disable the function being checked.</p>
-<p>It is useful if you want to check for the availability of functions
-such as <tt class="docutils literal"><span class="pre">eval()</span></tt> and <tt class="docutils literal"><span class="pre">exec()</span></tt>, which are dangerous and might be
-disabled on servers with highly restrictive security policies.</p>

-<p class="last">This function was introduced because Suhosin terminated
-script execution, but this turned out to be a bug. A fix
-has been available for some time (version 0.9.34), but is
-unfortunately not released yet.</p>
