<blockquote class="note"><p><strong class="note">Note</strong>:
<span class="simpara">
As of PHP 4.3.2, <span class="envar">PATH_TRANSLATED</span> is no longer set
implicitly under the Apache 2 <acronym title="Server Application Programming Interface">SAPI</acronym> in contrast
to the situation in Apache 1, where it's set to the same value as
the <span class="envar">SCRIPT_FILENAME</span> server variable when it's not
populated by Apache. This change was made to comply with the
<acronym title="Common Gateway Interface">CGI</acronym> specification that
<span class="envar">PATH_TRANSLATED</span> should only exist if
<span class="envar">PATH_INFO</span> is defined.
</span>
<span class="simpara">
Apache 2 users may use <em>AcceptPathInfo = On</em> inside
<var class="filename">httpd.conf</var> to define <span class="envar">PATH_INFO</span>.
