Is there a list of server requirements anywhere? 

had a look, but I can't find one. 

I am aware of the script by @Ryan Ashbrook but am looking for a physical list of PHP plugins etc.

Thanks

 

There is no specific list available unfortunately. We require all standard PHP extensions (those which would be enabled by default), plus GD and MBString 

Thanks.

I recall that there were various recommend php extensions in addition? 

or bits like database format etc?

 

'required' => array( 'dom', 'gd', 'mysqli', 'openssl', 'session', 'simplexml', 'xml', 'xmlreader', 'xmlwriter' ),

'advised' => array( 'phar', 'zip', 'exif' ),
