Uninitialized string offset on line 828

[phplaw]

Uninitialized string offset: 59 application/third_party/tcpdf/tcpdi_parser.php 828
The line on 828

$frag = $data{$offset} . @$data{$offset+1} . @$data{$offset+2} . @$data{$offset+3};

Should change to

$frag = isset($data{$offset}) ? $data{$offset} : '';
                $frag .= isset($data{$offset+1}) ? $data{$offset+1} : '';
                $frag .= isset($data{$offset+2}) ? $data{$offset+2} : '';
                $frag .= isset($data{$offset+3}) ? $data{$offset+3} : '';
