如何获得作曲家已知的PHP扩展名？ [关闭]

Question

I need to set up a composer.json with server requirements (eg. php >= 5.6, lib-xml, etc). There are some examples in composer documentation, but what i need is a method to get a composer alias (ext-xxx, lib-yyy, etc) for a given php extenstion or library (eg. php7.1-curl - Ubuntu package name).

Answer 1

Partial answer

composer show -p

Gives a list of extensions/libraries installed on the current system. So the solution is:

1. On a local linux/unix, install the library/extension in question (eg. apt install php-curl)

2. Filter the list of libraries recognized by composer to find the right result

   composer list -p | grep curl
