I have a somewhat complex but very helpful feature idea: a way to configure the PHP formatter to do advanced organization based on a configuration that can also organize blocks. This is really a dream of mine for the formatter. I appreciate any work that may go into implementing it!

Use declarations, classes, class variables, functions, etc. could be formatted based on a configuration.

Example for use declarations:

{
    "php.format.organizeUsings": {
        "enabled": false, // Allows this to be turned off so organizeUsings can remain on for other languages like JS

        "removeUnused": true // Remove unused use declarations
        
        // Orders by namespace with individual configuration
        "order": {
            "Doctrine": "ascending",
            "php": "ascending",

            // Default for any remaining namespaces
            "default": "ascending",
        },
        
        // Would place newline between groups in "order"
        "newlineBetweenGroups": true
    },
}

If enabled and document formatted:

use Doctrine\ORM{
    EntityRepository,
    Query
};

use DateTime;
use Exception;

Example for other blocks:

{
    "php.format.organizeBlocks": {
        "enabled": true,

        "baseOrder": {
            "abstract class": "ascending",
            "class": "ascending",
            "trait": "ascending",
        },

        // Order of groups of blocks by accessor
        "memberOrder": {
            // Accessor/keyword
            "default": {
                // Types: order
                "object": "ascending",
                "array": "ascending",
                "scalar": "ascending",
                
                // Default for any remaining types
                "default": "ascending",
            },
            
            "private": {
                // inherits default
            },
            
            "abstract": {
                // inherits default
            }
        },
    },
}

If enabled and document formatted:

abstract class MyAbstractClass
{
    myObj = { };
    private myArray = [];

    private myFunc() { }

    abstract myAbstractFunc();
}

class MyClass { }
class MySecondClass { }

trait MyTrait { }
