     If you wish to move a file, use the <function>rename</function> function.

    <note>
     <para>
      As of PHP 4.3.0, both <parameter>source</parameter> and
      <parameter>dest</parameter> may be URLs if the "fopen wrappers"
      have been enabled.  See <function>fopen</function> for more details.
      If <parameter>dest</parameter> is a URL, the copy operation may
      fail if the wrapper does not support overwriting of existing files.
     </para>
    </note>
    <warning>
     <para>
      If the destination file already exists, it will be overwritten.
     </para>
    </warning>
    <note>
     <para>
      Windows compatibility: If you copy a file with no size,
      <function>copy</function> will return &false;, but the file will be correctly
      copied.
     </para>
    </note>
    <para>
     See also <function>move_uploaded_file</function>,
     <function>rename</function>, and the section of the manual
