I updated my MacOS to Monterey (12.0.1) and my PHP stopped working. MacOS 12 seem to have removed PHP support.
I'm currently trying to configure everything using homebrew.
After installation, when I try to start the httpd, I'm getting the following errors-
user@Laptop folder % /opt/homebrew/opt/httpd/bin/httpd -D FOREGROUND
dyld[15738]: Symbol not found: _apr_bucket_file_set_buf_size
Referenced from: /opt/homebrew/Cellar/httpd/2.4.51/bin/httpd
Expected in: /usr/lib/libaprutil-1.0.dylib
zsh: abort /opt/homebrew/opt/httpd/bin/httpd -D FOREGROUND
Am I missing any package for _apr_bucket_file_set_buf_size?
Yeah, what a nightmare! PHP is no longer supported natively in MacOS 12. I switched to Homebrew's Apache (httpd) package.
But switching from native Apache to Homebrew's Apache wasn't easy.
There are lots of guides out there on how to install Homebrew's Apache. I won't go into them here.
But after installing, configuring, and starting, I was receiving a similar error to your "apr_bucket" error. I ran brew reinstall apr-util and that did the trick.

After that, I removed Homebrew's Apache brew remove httpd, then reinstalled brew install httpd, then updated the httpd.conf file, then started brew services start httpd. That seemed to do the trick for me.
I had to sign the homebrew PHP module using MacOS codesign.
Finally, Apache and PHP are working in my MacOS Monterey.
Kudos to the original author for the detailed solution
