<h2 class="title">PUT method support</h2>
<p class="para">
PHP provides support for the HTTP PUT method used by some clients to store
files on a server.
PUT requests are much simpler than a file upload using POST requests
and they look something like this:
<div class="informalexample">
<div class="example-contents">
<div class="HTTPcode"><pre class="HTTPcode">PUT /path/filename.html HTTP/1.1</pre>
</div>
</div>
</div>
</p>
<p class="para">
This would normally mean that the remote client would like to save
the content that follows as: <var class="filename">/path/filename.html</var> in your web tree.
It is obviously not a good idea for Apache or PHP to automatically
let everybody overwrite any files in your web tree. So, to handle
such a request you have to first tell your web server that you
want a certain PHP script to handle the request. In Apache you do
this with the <em class="emphasis">Script</em> directive. It can be
placed almost anywhere in your Apache configuration file. A
common place is inside a <em><Directory></em> block or perhaps inside
a <em><VirtualHost></em> block. A line like this would do the trick:
<div class="informalexample">
<div class="example-contents">
<div class="cdata"><pre>
Script PUT /put.php
</pre></div>
</div>
</div>
</p>
<p class="simpara">
This tells Apache to send all PUT requests for URIs that match the
context in which you put this line to the <var class="filename">put.php</var> script. This
assumes, of course, that you have PHP enabled for the <var class="filename">.php</var>
extension and PHP is active. The destination resource for all PUT
requests to this script has to be the script itself, not a filename the
uploaded file should have.
</p>
<p class="simpara">
With PHP you would then do something like the following in
your put.php. This would copy the contents of the uploaded file to the
file <var class="filename">myputfile.ext</var> on the server.
You would probably want to perform some checks and/or
authenticate the user before performing this file copy.
