32 bits builds of PHP

[stof]

Describe the feature
Consider providing 32bit builds of PHP

Version

• I have checked releases, and the feature is missing in the latest patch version of v2.

Underlying issue
Most CI setups of libraries are currently using PHP 64 bits builds. And then, from time to time, they receive issues like scssphp/scssphp#51 reporting bugs affecting only the 32 bits version of PHP.
Being able to have a CI running on a 32 bits build would help avoiding such cases (and preventing regressions).

Describe alternatives

• Make php 32 bit die => not something we can do as library maintainers (even though it would simplify our issue...). That's something that the PHP core team would have to do, and I'm not aware of any plan to mandate 64 builds.
• Maintain our own build of PHP for a 32 bits job. Symfony went with this option by using a 32 bit build in its Appveyor setup (but testing 32 bits and Windows at the same time might not be the best choice as we might need a matrix instead). But that requires more work.

Additional context

Are you willing to submit a PR?
I'm not familiar with the way this project works and where it takes PHP from, so not sure I can help.

@shivammathur sorry, I missing that in the search.
What about including some doc about that rather than relying on a comment in a closed issue ?

[shivammathur]

Yes, you are right.
I will add this to the documentation.

@shivammathur should this issue be re-opened until the doc gets updated so that it does not get forgotten ?
