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