After updating PHP 7.4 to PHP 8.1 RC5, PHP has stopped working on my machine and produces following error:

PHP Warning: PHP Startup: ^(text/|application/xhtml+xml) (offset=0): unrecognised compile-time option bit(s) in Unknown on line 0

it produces the error even when I ask for php version:

PHP Warning:  PHP Startup: ^(text/|application/xhtml\+xml) (offset=0): unrecognised compile-time option bit(s) in Unknown on line 0
PHP 8.1.0RC5 (cli) (built: Nov  4 2021 14:57:53) (NTS)

updated using this repository:

sudo add-apt-repository ppa:ondrej/php

do you know what the problem could be?

Under debian (i think is same for ubuntu), I fixed by doing:

sudo apt-get install libpcre2-8-0

Like @Douglas Roos said in comments,

sudo apt update
sudo apt upgrade

Will fix your problem.

The problem is solved, just update the repository and re-install PHP 8.1. I think it was just in RC5
