<p class="intro">With PHP, it is possible to upload files to the server.</p>
<hr />
<h2>Create an Upload-File Form</h2>
<p>To allow users to upload files from a form can be very useful. </p>
<p>Look at the following HTML form for uploading files:</p>
<table width="100%" border="1" class="ex" cellspacing="0">
<tr><td>
<pre><html>
<body></pre>
<pre><form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form></pre>
<pre></body>
</html></pre>
</td></tr></table>
<p>Notice the following about the HTML form above:</p>
<ul>
<li>The enctype attribute of the <form> tag specifies which content-type to use when
submitting the form. "multipart/form-data" is used when a form requires
binary data, like the contents of a file, to be uploaded</li>
<li>The type="file" attribute of the <input> tag specifies that the input should
be processed as a file. For example, when viewed in a browser, there will be
a browse-button next to the input field</li>
</ul>
<p><b>Note:</b> Allowing users to upload files is a big security risk. Only permit
trusted users
to perform file uploads.<br />
</p>
<hr />
<h2>Create The Upload Script</h2>
<p>The "upload_file.php" file contains the code for uploading a file:</p>
