Summary12713: Undefined offset: 1 in SPSS export function

If I want to export the Responses of one of my surveys to SPSS, I get an error when trying to export the syntax file. The first ~100 lines are OK and then some HTML code is added to the *.sps file. It seems to be an PHP Stack Trace.

Steps To Reproduce
  • Create a survey
  • open the survey
  • Responses => Responses & statistics
  • Export => Export results to a SPSS/PASW command file
  • leave everything on default
  • click Export syntax

-> download starts and finishes without error but then there is a php error in the file

Additional Information

I know I use an older version of limesurvey, but the code of the export.php (in which the error occurs) isn't changed since this version.

Since this error only occurs in one of our surveys, it is probably hard to reproduce. But I think the strack trace is quite helpful.
I took a look at the stack trace and it shows an Undefined offset of an array. After taking a closer look on the code, it seemed to me that there is a little mistake in the code:

  • you iterate over every element of $label_parts
  • you stop at the last element of the array $label_parts
  • but you always access the current element and the next element
  • at the last element you cannot access the next element => Array out of bound exception or in php language: Undefined offset:1

I solved it for now with a dirty workaround by checking if the "$idx+1"th element exists and only then it tries to access it. But I guess it doesn't solve the problem. I guess a better variant is to create a new array with "count($label_parts) + 1" elements and add the quotes. But since I don't really understand what code block exactly does, I cannot tell for sure.

Of course feel free to ask for additional info.
