Get characters which are not in brackets REGEX

I'm basically working on custom query building. I've designed the pattern as field_set and sub_field_sets. A sample Query:
({e:3}.{f:44}.{f:2}) + (
({e:3}.{f:44}.{f:3}) + ({e:3}.{f:44}.{f:4})
) - ({e:3}.{f:44}.{f:5})
I want to get all operators from root using REGEX. Which in this case should result ['+', '-'] and NOT ['+', '+', '-']

It's quite unclear what you're asking. You need to provide more examples, give us the list of possible operators, etc. From what you posted, usingstrpos($query, $operator) !== falsefor each operator should work, at least...

You can shorten your regex a bit with removing the escapes for+and-in character classes. They are not required if these are only characters in the character class.

You can shorten your regex a bit with removing the escapes for
+ and - in character classes. They are not required if these are only characters in the character class.– Asunez
