<h1>Common troubles that mirrors of PHP.net face</h1>
<p>
 Mirroring the PHP.net website requires a few specific settings and
 considerations, and this document provides a list of problems with possible
 solutions. The [<strong>?</strong>] link within each title may be used to
 test this mirror.
</p>

<a name="multiviews"></a>
<h3>MultiViews are on [<a href="/functions">?</a>]</h3>
<p>
 Because the 'Options' directive may be ignored in VirtualHost, a
 solution is to move the MultiViews option into a specific
 directory and disable it from there. For example:
</p>
<pre class="info">
  &lt;VirtualHost *:80&gt;
    &lt;Directory /path/to/phpweb&gt;
      Options -Indexes -MultiViews
    &lt;/Directory&gt;

    DocumentRoot /path/to/phpweb
    ServerName ....
    ....
  &lt;/VirtualHost&gt;
</pre>
<p>
 The <a href="mirroring.php#settings">mirror settings</a> example also
 demonstrates this use. See also the Apache documentation that describes
 <a href="http://httpd.apache.org/docs/content-negotiation.html">
 Content Negotiation</a>.
</p>

<a name="content-type"></a>
<h3>Improper Content-Type [<a href="/manual/en/faq.html.php">?</a>]</h3>
<p>
 Some pages are returning incorrect <code>Content-Type</code> headers. For example,
 xx.php.net/manual/en/faq.html.php should be returning <code>text/html</code>
 instead of <code>application/x-httpd-php</code>. See also the Apache
 documentation describing
 <a href="http://httpd.apache.org/docs/content-negotiation.html">Content
 Negotiation</a>. This problem might be specific to
 <a href="http://apache.lexa.ru/">Russian Apache</a>.
</p>

<a name="manual-redirect"></a>
<h3>Manual redirects [<a href="/manual/">?</a>]</h3>
<p>
 By default, Apache inserts an alias for <code>/manual/</code> in the configuration
 and this causes problems for mirrors. So for example if you find that
 the manuals are listed on the documentation page but all of the links
 open up a search page, you probably suffer from this problem and must
 remove that alias.
</p>

<a name="shortcuts"></a>
<h3>Broken manual shortcuts [<a href="/echo">?</a>]</h3>
<p>
 If the shortcut features [e.g. xx.php.net/echo] are not working, be sure
 the manual files are really under <code>DOCUMENT_ROOT</code> and that the English
 manual files are present. Also make sure that you have a correct
 ErrorDocument setting.
</p>

<a name="invalid-data"></a>
<h3>Invalid data types [<a href="/testing">?</a>]</h3>
<p>
 Invalid data is being received, and this is probably caused by improper error
 handler settings. See the <a href="mirroring.php">mirror guidelines</a>
 for how to setup the ErrorDocument.
</p>

<a name="var"></a>
<h3>A misguided var handler [<a href="/manual/en/ref.var.php">?</a>]</h3>
<p>
 The <a href="mirroring.php">mirroring guidelines</a> mention that Apache2
 enables a 'var' handler by default and this may be disabled by using
 <code>RemoveHandler var</code> in the configuration file.
</p>

<a name="msi"></a>
<h3>Mishandling of .msi files</h3>
<p>
 When improperly set, users are not given a "download this file" prompt
 when attempting to download the PHP Installer (a .msi file). Your web
 server configuration should be adjusted to force .msi files as
 'application/octet-stream'. In Apache this may be done by using:
 <code>AddType application/octet-stream .msi</code>
</p>

<a name="outbound"></a>
<h3>Unable to do external searches [<a href="results.php?q=curl&p=manual&l=en">?</a>]</h3>
<p>
 Several searches require outbound connections to www.php.net, so this is
 a test for that. The www.php.net box then connects to a third-party search engine.
