咨询：Heroku是否支持PHP原生C扩展（.so文件）？

Hey there, let's break down your question step by step:

核心问题：Heroku是否支持自定义PHP原生C扩展（.so文件）？ #

Short answer: Yes, but you can't just upload pre-compiled .so files directly — Heroku's runtime environment (Ubuntu-based) is likely different from your local setup, so pre-built extensions will almost certainly fail to load. Instead, you need to compile the extension during the Heroku build process.

具体实现方式 #

Since you're using SWIG to generate your extension, here's how you can make this work on Heroku:

• Include your extension's C source code, SWIG interface files, and any build scripts in your project repository.
• Configure your composer.json to run the compilation steps as part of the install process. For example, add a post-install-cmd script that runs:

  phpize
  ./configure
  make
  make install
  

• Make sure to add the extension to your php.ini file (or a .user.ini in your web root) so PHP loads it at runtime.

关于PHP 5.6的重要提醒 #

Heroku's official PHP buildpack no longer supports PHP 5.6 (since PHP 5.6 reached end-of-life years ago). To run PHP 5.6 on Heroku, you'll need to:

• Use a third-party PHP 5.6 buildpack, or
• Create a custom Docker image with PHP 5.6 and your extension pre-compiled, then deploy that image to Heroku.

关于工单的小提示 #

While you can't submit a ticket without an app yet, once you create a test app (even a minimal one), you can reach out to Heroku support for more specific help with your extension's build process.
