Bug description

I specifically need Memcached installed to run our local test suite, and the current iteration of Herd does not include the module by default. I compiled the memcached module using the instructions here.

Here is my current php.ini file at ~/Library/Application Support/Herd/config/php/83/php.ini:

extension=/opt/homebrew/lib/php/pecl/20230831/memcached.so

auto_prepend_file = /Users/<redacted>/.composer/vendor/spatie/global-ray/src/scripts/global-ray-loader.php
curl.cainfo=/Users/<redacted>/Library/Application Support/Herd/config/php/cacert.pem
openssl.cafile=/Users/<redacted>/Library/Application Support/Herd/config/php/cacert.pem
pcre.jit=0

memory_limit=2048M
upload_max_filesize=2M

zend_extension=/Applications/Herd.app/Contents/Resources/xdebug/xdebug-83-arm64.so
xdebug.mode=debug,develop
xdebug.start_with_request=yes
xdebug.start_upon_error=yes
xdebug.log_level=0

Here's my installed version:

$ which php && php -v
/Users/<redacted>/Library/Application Support/Herd/bin/php
PHP 8.3.6 (cli) (built: Apr 12 2024 00:13:56) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.3.6, Copyright (c) Zend Technologies
    with Zend OPcache v8.3.6, Copyright (c), by Zend Technologies

And here's the output when using php -m on the CLI (with and without specifying the config manually)

$ herd php -m | grep -i memcached
$ herd php -c ~/Library/Application\ Support/Herd/config/php/83/php.ini -m | grep -i memcached
memcached
$

I assuming this is a bug based on this snippet from the Changing PHP.ini settings page of the docs:

The changes will be immediately available to the PHP CLI version, but you will need to restart all Herd services to apply the changes to HTTP requests via nginx.

What do you get when you run herd php --ini?

[trueparallels]

$ herd php --ini
Configuration File (php.ini) Path: /lib
Loaded Configuration File:         (none)
Scan for additional .ini files in: (none)
Additional .ini files parsed:      (none)

Which shell are you using?
Herd uses environment variables to load php.ini files.

For example:

export HERD_PHP_83_INI_SCAN_DIR="/Users/marcelpociot/Library/Application Support/Herd/config/php/83/"

But herd php -v gives you PHP 8.3.6?

[trueparallels]

I'm using Fish shell. I don't have any Herd-specific environment variables set. herd php -v does indeed give me 8.3.6.

Am I get some sort of weird experience because I'm not using Herd in the context of a parked site(s)? Our applications are not Laravel currently, and I'm not using the parked directory features because all our stuff is Dockerized on local.

[mpociot]

You don't need to use the parked directory feature as you can also just manually link sites, that's not a problem.

The fish shell is not officially supported, which is why you're missing the environment variables.

Ah, ok. Thanks for all your help.

Out of curiosity, how does that work? Is Herd just appending exports to .bashrc/.zshrc?

It might be helpful to add this information to the documentation, as it's a bit misleading — it gives the impression that it should work with Fish after adding the path using fish_add_path.

Took me a while to figure this out — glad I finally found the info here.
