Undefined symbol: zend_type_to_string - php

Question

I'm a bit new on ArchLinux but I have installed PHP 7 with pacman and after that Xdebug but Xdebug install the package php ( that is PHP 8 ).
When I tried to launch PHP 7 I got the following message and Xdebug doesn't work:
PHP Warning: Failed loading Zend extension 'xdebug.so' (tried: /usr/lib/php7/modules/xdebug.so (/usr/lib/php7/modules/xdebug.so: undefined symbol: zend_type_to_string), /usr/lib/php7/modules/xdebug.so.so (/usr/lib/php7/modules/xdebug.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0
That's my /etc/php7/conf.d/xdebug.ini
zend_extension=xdebug.so
;xdebug.remote_enable=on
;xdebug.remote_host=127.0.0.1
;xdebug.remote_port=9000
;xdebug.remote_handler=dbgp
;xdebug.start_with_request=yes
;xdebug.mode=debug
So if someone have the solution :)

Answer 1

I had the same problem.
So, I uninstalled PHP 8 and installed Xdebug for PHP 7.4:
yay -S xdebug7

Answer 2

I found the solution here !
$ asp update xdebug
$ asp export xdebug
After that i updated the PKGBUILD
$ cat PKGBUILD
