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="cdata"><pre>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 <Directory> block or perhaps inside a <VirtualHost> 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 put.php script. This assumes, of course, that you have PHP enabled for the .php 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. </p> <p class="para"> <div class="example"> <p><b>Example #1 Saving HTTP PUT files</b></p> <div class="example-contents"><div class="phpcode"><code><span style="color: #000000"><span style="color: #0000BB"><?php<br /></span><span style="color: #FF8000">/* PUT data comes in on the stdin stream */<br /></span><span style="color: #0000BB">$putdata </span><span style="color: #007700">= </span><span style="color: #0000BB">fopen</span><span style="color: #007700">(</span><span style="color: #DD0000">"php://input"</span><span style="color: #007700">, </span><span style="color: #DD0000">"r"</span><span style="color: #007700">);<br /><br /></span><span style="color: #FF8000">/* Open a file for writing */<br /></span><span style="color: #0000BB">$fp </span><span style="color: #007700">= </span><span style="color: #0000BB">fopen</span><span style="color: #007700">(</span><span style="color: #DD0000">"myputfile.ext"</span><span style="color: #007700">, </span><span style="color: #DD0000">"w"</span><span style="color: #007700">);<br /><br /></span><span style="color: #FF8000">/* Read the data 1 KB at a time<br /> and write to the file */<br /></span><span style="color: #007700">while (</span><span style="color: #0000BB">$data </span><span style="color: #007700">= </span><span style="color: #0000BB">fread</span><span style="color: #007700">(</span><span style="color: #0000BB">$putdata</span><span style="color: #007700">, </span><span style="color: #0000BB">1024</span><span style="color: #007700">))<br /> </span><span style="color: #0000BB">fwrite</span><span style="color: #007700">(</span><span style="color: #0000BB">$fp</span><span style="color: #007700">, </span><span style="color: #0000BB">$data</span><span style="color: #007700">);<br /><br /></span><span style="color: #FF8000">/* Close the streams */<br /></span><span style="color: #0000BB">fclose</span><span style="color: #007700">(</span><span style="color: #0000BB">$fp</span><span style="color: #007700">);<br /></span><span style="color: #0000BB">fclose</span><span style="color: #007700">(</span><span style="color: #0000BB">$putdata</span><span style="color: #007700">);<br /></span><span style="color: #0000BB">?></span></span></code></div> </div> </div> </p> </div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="features.file-upload.html">Handling file uploads</a></div> <div class="next" style="text-align: right; float: right;"><a href="features.remote-files.html">Using remote files</a></div> <div class="up"><a href="features.file-upload.html">Handling file uploads</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>⌨️ 快捷键说明
