php code display the code instead of output
<p>Can someone please explain this code, i am following a very good book that was recommended to me and I have typed the code exactly as it is in the book. it displays the code instead of out, I am not sure what is wrong, the code is from a book called php solutions</p>

<pre><code>          &lt;?php
                     // set the max upload size in bytes
                      $max = 51200;
                     if(isset($_POST['upload'])){

                // define the path to the upload folder
                $destination = 'C:\upload_test';
                 // move the file to the uplaod folder and rename it
                move_uploaded_file($_FILES['image']
                    ['tmp_name'],     $destination.$_FILES['image']['setara']);

                    }
                    ?&gt;







    &lt;!doctype html&gt;
    &lt;html  lang="en"&gt;
    &lt;head&gt;
    &lt;meta charset="utf-8"&gt;
    &lt;title&gt;Mult&lt;/title&gt;
    &lt;link rel="stylesheet" type="text/css" href="css/style.css"&gt;
    &lt;/head&gt;
    &lt;body&gt;





    &lt;form action="" method="post" enctype="mutipar/form-data" id="uploadImage"&gt;
        &lt;p&gt;
            &lt;label for="image"&gt;Upload image:&lt;/label&gt;
            &lt;input type="hidden"name="MAX_FILE_SIZE" value="&lt;?php echo $max; ?&gt;"&gt;

            &lt;input type="file" name="image" id="image"&gt;
        &lt;/p&gt;
        &lt;p&gt;
            &lt;input type="submit" name="upload" id="upload" value="Upload"&gt;
        &lt;/p&gt;
    &lt;/form&gt;






&lt;/body&gt;
&lt;/html&gt;
