Uninitialized string offset: 35 on line 725 tcpdi_parser.php

[Manitnelav]

I get this error
Uninitialized string offset: 35 application/third_party/tcpdf/tcpdi_parser.php 725

The line on 725 is in method getRawObject

while (strspn($data[$offset], "\x00\x09\x0a\x0c\x0d\x20") == 1) {
    $offset++;
}

Some idea how to change it? I don't understand what getRawObject should return in this cases.

I was able to fix the issue by adding isset and strict type checking, which seems to resolve the infinite loop. However, I'm not sure if this is the most robust solution. Here's the code I modified at line 725:

while (isset($data[$offset]) && is_string($data[$offset]) && strspn($data[$offset], "\x00\x09\x0a\x0c\x0d\x20") == 1) { $offset++; } // get first char if (isset($data[$offset]) && is_string($data[$offset])) { $char = $data[$offset]; } else { return array(array(PDF_TYPE_NULL, 'null'), $offset); }
