What are PHP required extensions for Q2A?

Question

I'm thinking of upgrade PHP version, so I need a list of required PHP extensions for Q2A.

I can't find a document for this.

Answer 1

For the base system you're going to need/want these modules:

• php-gd
• php-json
• php-mbstring
• php-mysql
• php-opcache
• php-readline
• php-xml

Plugins may or may not require additional PHP modules.

I think we may need hash (for passwords), and session (for sessions), probably a few more things like something to resize images. Maybe only the original creator of Q2A will have a full list of all required functions. Currently, the best way is to take a screenshot of last known good PHP extensions.
