php将文件上传到服务器并重命名

html表单代码如下所示：

<form action=\"<?php print $PHP_SELF?>\" enctype=\"multipart/form-data\" method=\"post\">
   Last Name:<br /> <input type=\"text\" name=\"name\" value=\"\" /><br />
   Class Notes:<br /> <input type=\"file\" name=\"classnotes\" value=\"\" /><br />
   <p><input type=\"submit\" name=\"submit\" value=\"Submit Notes\" /></p>
</form>

php上传文件及重命名文件代码如下：

<?php
   define (\"FILEREPOSITORY\",\"./\");

   if (is_uploaded_file($_FILES[\'classnotes\'][\'tmp_name\'])) {

      if ($_FILES[\'classnotes\'][\'type\'] != \"application/pdf\") {
         echo \"<p>Class notes must be uploaded in PDF format.</p>\";
      } else {
         /* http://www.manongjc.com/article/1391.html */
         $name = $_POST[\'name\'];
         $result = move_uploaded_file($_FILES[\'classnotes\'][\'tmp_name\'], FILEREPOSITORY.\"/$name.pdf\");
         if ($result == 1) echo \"<p>File successfully uploaded.</p>\";
         else echo \"<p>There was a problem uploading the file.</p>\";
      } #endIF
   } #endIF
?>
