RegEx - Match all unquoted strings in brackets except if they are all capital-letters

In PHP 7.2, the manual says:

Unquoted strings that are non-existent global constants are taken to
be strings of themselves. This behaviour used to emit an E_NOTICE, but
will now emit an E_WARNING. In the next major version of PHP, an Error
exception will be thrown instead.

Also, code like this $list[products_name], will now produce this warning:

$list[products_name]

Warning: Use of undefined constant products_name - assumed 'products_name'
(this will throw an Error in a future version of PHP) in %s on line %d

I have now switched to PHP 7.2 and got such code that I would like to search and replace, by matching all unqoted strings inside brackets and add single-quotes to them (eg. $list[products_name] will become $list['products_name']), except for strings that are all capital. The reason I want to skip those specifically is because many times they are indeed constants and I shouldn't put them inside quotes.
I am new to regex and tried several options. So far, I have come up with this regex:

$list[products_name]

$list['products_name']

$w+[([a-zA-Z_]+[w]+)]


It works well for most purposes I need it, except it still captures all capital strings in code blocks like this:

$options[$list[_option_id]]=array($list[_value],$list[_value_id]);
$option_names[$list[_option_id1]]=$list[_option];
$product_name=$list[products_name];
$product_name=$list[0];
$product_name=$list[DONTCAPTUREME];
$product_name=$list[CapTureMe];
$product_name=$list[CapTurEME];


DEMO

How can I modify it to not match only examples like DONTCAPTUREME?

DONTCAPTUREME

Thank you

Right after the first [, use negative lookahead for all-caps followed by ]:

[

]

$w+[(?![A-Z]+])([a-zA-Z_]+[w]+)]
^^^^^^^^^^^^

DONT_CAPTURE_ME

$w+[(?![A-Z_]+])([a-zA-Z_]+[w]+)]

_

]

$w+[(?=[^]]*[a-z])([a-zA-Z_]+[w]+)]

also skips many other ones

$actionKey = $get[AM_ACTION_GET_VARIABLE];

Finally the solution that worked best for me (using grepWin) is:

Search (case sensitive must be enabled):

(").*?1(*SKIP)(*FAIL)|$w+]?[(?!w*(|w*:)(?=[^]]*[a-z])(K[a-zA-Z_]+[w]+)


Replace with:

'2'


Always backup your files before such operation.
