我有一个广泛使用 PDO 的 php 应用程序，并且有一个具有 informix 的新客户端。以前我们使用 php 5.2 没有任何问题，但切换到 PHP 5.3 是不可避免的，所以：
有人找到了在 php5.3 上使用 php_pdo_informix 的方法，还是它完全过时了，我必须找到另一种选择？
这对于我们的测试环境 (CentOS) 是必需的，但开发人员目前在 Windows 上工作，我们有类似的问题。有一个 php_pdo_informix.dll 但它是针对 php5.2 编译的并且拒绝在 php5.3 上加载
有人有php5.3的dll吗？
谢谢
我已经尝试过：
$ sudo pecl install pdo_informix
pecl.php.net is using a unsupported protocol - This should never happen.
pecl/PDO_INFORMIX requires package "pear/PDO"
No valid packages found
install failed
或者
pecl install --alldeps pdo_informix
表明它依赖于 pear/PDO，但在 5.3 中已被弃用
并且使用显式版本 1.2.6 、 1.2.7 无济于事
即使我尝试安装 pear/PDO，它也会失败并出现许多错误，这是预期的，因为 PHP 中有许多 API 更改会中断。
尝试预先安装 pdo 时出现这种错误：（省略了某些行）
$ sudo pecl install pdo

如果我尝试安装特定的 pdo_informix 版本，我会得到以下输出：
