     (including socket timeout); otherwise returns &false;.

      <simpara>
       If a connection opened by <function>fsockopen</function> wasn't closed
       by the server, <function>feof</function> will wait until a timeout has
       been reached to return &true;. The default timeout value is 60 seconds.
       You may use <function>stream_set_timeout</function> to change this
       value.

      <para>
       If passed file pointer is not valid you may get an infinite loop, because
       EOF fails to return TRUE.
