我不可避免地需要开发基于PHP 5.4的系统。我知道这是远远超出安全更新，但这是我现在所拥有的。我希望创建一个PHP 5.4 Docker镜像用于开发目的。从历史上看，我和我的团队一直在使用基于Centos的PHP 5.6图像，因为没有5.4 Centos图像可用。
因此，我正在尝试编译PHP 5.4。经过大量的尝试和错误，我可以用最少的编译扩展来编译PHP，然后在顶部使用一堆可动态加载的扩展。这意味着我的各种下游项目可以通过添加正确的php.ini扩展命令来选择他们需要的扩展。
这是我的Dockerfile:

# well out of support. Centos has been chosen to mirror live
# servers.

这是一个意外的编译错误——"参数太多"感觉像是库不匹配之类的，但我特别选择了1.11，这是生产服务器上扩展的版本。可能是我的libzip-devel版本太新了吗？如果是的话，我能获得一个更早的版本，并让它在Centos的维护版本中工作吗？
我在任何其他扩展上都没有遇到过这个问题，所以也许这只是运气不好，我在最后一个扩展上遇到了一个骗子问题！
更新
我使用的Centos版本中libzip-devel的本机版本为0.10.1，与生产服务器(通过php -i(报告的libzip版本相匹配。以下是Docker图像中的信息：

我怀疑改变我的C编译器是否会有所帮助，但我肯定对这个方向的想法持开放态度。
我终于解决了这个问题。
如果记录什么不起作用是有帮助的，我首先注意到我有一个补丁级别的PHP版本差异。我的生产服务器在5.4.16上，我是为5.4.45构建的。我对此进行了调整，确信它会下载正确的代码来与其他库链接，结果发现它没有什么不同。
然后，我分析了我必须在pecl-zip扩展中增加多少版本号才能获得下一个可用的稳定版本，从zip-1.11.0到zip-1.112.3。这个汇编很好。这并不理想，因为我的生产服务器确实将zip 1.11.0与PHP 5.4.16混合在一起，但没关系，我们已经使用5.6开发了大约一年，尽管我们的生产目标是5.4。因此，新形象仍然是一个实质性的胜利，因为它让我们更接近我们的生活环境。
