There should be no error in this code, and that line should not generate any error.

What is the exact error message that you are getting?

from phpspreadsheet.

I have seen cases where user-supplied error handlers have inappropriately detected and converted the suppressed deprecation message to an error despite the use of the at-sign to suppress messages. That is the reason for the check on testAutodetect in the code cited above. Users unwilling to correct their error handler can add $reader->setTestAutodetect(false) to their code before loading the spreadsheet; they will prematurely lose the ability to detect Mac line endings (which is very unlikely to be an issue), and the error message will go away because ini_set will not be called.
