How to fix associative array keys that lack single quotation marks in multiple files

Upgrading some really old PHP code and need to find all occurrences of array access without quotation mars (" and '). Should match [abc] but not ["abc"] or ['abc']. My regex works, but it also matches the $ character(like [$abc]), which i don't want.
Here is my full regex: [[^"'][A-Za-z0-9]+][^"'] https://regex101.com/r/uJM6DQ/1
How can I make it stop matching the $ character? Why does it match the $ character even if I never ask regex to match it?

Perhaps add it to the first negated character class[[^$"'][A-Za-z0-9]+][^"']

Haha, good point, that solves the problem. Thanks! But do you know why it matches the $ in the first place?

"even if I never ask regex to match it": You do ask to match it with the negative class:[^"']. You'll agree that$complies with that (among many other characters)

Because you use a negated character class[^"']. The negated character class matches any character that is not in the character class.
