  <simpara> 
   Identical to calling <function>fopen</function>, <function>fwrite</function>,
   and <function>fclose</function> successively.
  </simpara>
  <para>
   You can also specify the <parameter>data</parameter> parameter as an array
   (not multi-dimension arrays). This is equivalent to
   <literal>file_put_contents($filename, join('', $array))</literal>.
  </para>
  <para>
   As of PHP 5.1.0, you may also pass a stream resource to the
   <parameter>data</parameter> parameter. In result, the remaining buffer of
   that stream will be copied to the specified file. This is similar with
   using <function>stream_copy_to_stream</function>.
