That's an awesome feature to increase Castor adoption. Thanks 💛

A small note related to my early comment

The subset of extensions chosen to be compiled currently in the binary is really small, it was designed to run a simple "Hello World".

My concern would be people trying to use it in their own real world Castor projects and hitting errors straight away. This would be a subpar experience.

Could we find a right balance of php extensions to include natively without bloating the binary too much ?

Maybe we could take insipiration from the official docker image, running docker run --rm php:8.3-alpine php -m gives :

[PHP Modules]
Core
ctype
curl
date
dom
fileinfo
filter
hash
iconv
json
libxml
mbstring
mysqlnd
openssl
pcre
PDO
pdo_sqlite
Phar
posix
random
readline
Reflection
session
SimpleXML
sodium
SPL
sqlite3
standard
tokenizer
xml
xmlreader
xmlwriter
zlib

Or maybe introducing a slim and normal version like docker official image tend to do would cover most use cases ?

ATM, the static binary weight <5mb, this is quite light IMHO.
What extension are missing?

[tigitz]

The comparison with the official PHP Docker image reveals that the following extensions are absent:

• ctype
• curl
• dom
• fileinfo
• filter
• iconv
• mysqlnd
• openssl
• PDO
• pdo_sqlite
• readline
• session
• SimpleXML
• sodium
• sqlite3
• xml
• xmlreader
• xmlwriter

Incorporating all these extensions (bin/castor compile tools/phar/build/castor.linux-amd64.phar --php-extensions=mbstring,phar,posix,tokenizer,pcntl,ctype,curl,dom,fileinfo,filter,iconv,mysqlnd,openssl,pdo,pdo_sqlite,readline,session,simplexml,sodium,sqlite3,xml,xmlreader,xmlwriter) extends the build time to 4 minutes on my machine, which includes the time taken to download the extensions, from the prior 1 minute and 20 seconds.

This also increases the size of the build from 9MB to 28M.

However, it's worth noting that the default libraries in the Docker image are selected not merely for their popularity but due to the complexity involved in installing them manually, as discussed here.

Given this, it may be beneficial for Castor to determine its own default set of PHP extensions. For my projects, I typically add:

• ctype
• curl
• dom
• PDO
• pdo_pgsql
• openssl
• sodium

This selection, excluding the specific requirement for pdo_pgsql, seems to offer a balanced extension of the default library, albeit increasing the size to 18M, which is a significant jump.

[lyrixx]

Size is 28M vs 9MB before.

something is strange on you computer. on github, it's only 4mb. see this build.

I'll made some bench with

ctype
curl
dom
PDO
pdo_pgsql
openssl
sodium

you really do some nice things with castor :D

Not sure what's going on but I've tried from a freshly cloned project, phar is the same size from build but binary is still around 9M 🤷‍♂️

Maybe others experience the same issue ?

Yeah 😅 I manage backup scripts, send emails, scrape the latest update of a webpage, and have my own vault secret management based on symfony one among other things. It's all about devops automation.

For the record, we had some concerns about security of the tool chain.

We use https://github.com/dixyes/phpmicro and we didn't review all the code. But this packages is used a lot by Laravel (herd, native php, etc)

So I think it's fine and I'll merge this PR since it's a real game changer !
