AWS elastic beanstalk上安装了哪些默认php扩展？

我需要知道默认情况下AWS elastic beanstalk php平台上安装了哪些扩展，但amazon的文档中似乎没有这些信息（除了含糊不清地说某些扩展是默认安装的）

有没有人知道这些信息在哪里，或者，如果没有，我怎么能自己弄清楚

---

我正在运行AWS elastic beanstalk平台

PHP7.1.32

我也遇到了同样的问题，我在任何地方都找不到任何官方信息，所以我最终只是通过ssh连接到elastic beanstalk创建的ec2实例，并运行正确的命令来确定默认安装的PHP扩展

我按照这个答案将ssh导入ec2实例：

然后我在ec2实例上运行了

php-r“print_r（get_-loaded_extensions（））”

这给了我所有安装的默认扩展的列表，特别是针对AWS提供的“64位Amazon Linux/2.6.1平台上运行的PHP7.1”
