<p class="para">As of PHP 4.3.3 you can use this function with the
<a href="book.nsapi.html" class="link">NSAPI server module</a> in Netscape/iPlanet/SunONE

<td>4.3.0</td>
<td>
Became an alias for <span class="function"><a href="function.apache-request-headers.html" class="function">apache_request_headers()</a></span>.
