Support for 32 bit builds of PHP

[danog]

Describe the feature
Thanks for the awesome project!
It would be great if you could also specify the architecture of binaries about to be installed, I would like to run my tests on 32-bit versions of PHP, too.

By default 64 bit PHP is installed, except on Windows for PHP 5.6 and below which is 32 bit.

I have no plans to adding cross-platform support for specifying the architecture directly as an input unless someone sponsors this work.
But on Ubuntu for PHP 5.6 to 7.4, you can use shivammathur/node docker images as a container and run setup-php manually to get both 32 bit and 64 bit PHP.

Here is a test workflow.

name: Multiarch workflow
on:
  push:
jobs:
  run:
    runs-on: ubuntu-latest
    container: shivammathur/node:latest-${{ matrix.arch }}
    strategy:
      matrix:
        arch: ["amd64", "i386"]
    steps:
      - name: Install PHP
        run: |
          # Update spc (See https://github.com/shivammathur/spc for options)
          spc -U

          # Install PHP
          spc --php-version "7.4" \
              --extensions "mbstring, intl" \
              --ini-values "post_max_size=256M, short_open_tag=On" \
              --coverage "xdebug" \
              --tools "php-cs-fixer, phpunit"
      - name: check int size
        # PHP_INT_SIZE is 4 for 32 bit and 8 for 64 bit
        run: php -r "echo PHP_INT_SIZE;"

Thanks!

i can't get it working.

I can't use actions/checkout and I can't install git to clone the repo. How to make it work?

@danon
I have fixed this in our shivammathur/node x86 images (shivammathur/node-docker@ac95d44) and now actions should work using the normal syntax on them (spc is not required anymore). I will update the documentation about this in the next release.
