In PHP 8.1, the auto_detect_line_endings INI directive has been deprecated, not deleted.

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?

[oleibman]

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.
