I write a PCRE trying to match dollar signs ($) only if they are between the curly braces.
My example text is like that:
Lorem $100 ipsum dolor {value$banana} sit $500 amet.
The pattern (?<=\{)(.*?)(?=\}) gives me everything between the curly braces ({value$banana}), but I need to exactly match the dollar sign in between. I do not need a pattern matching multiple occurrences.
I've been trying to work on this but could not find the answer anywhere. Thanks in advance!
If you only want to match a single $ inside curly braces just once you may use
'~\{[^{}$]*\K\$(?=[^{}]*})~'
See the regex demo
Details
\{ - a { char[^{}$]* - 0 or more chars other than {, } and $ \K - match reset operator discarding all text matched so far from the match memory buffer\$ - a $ char(?=[^{}]*}) - a positive lookahead that requires the presence of any 0+ chars other than { and } and then a } immediately to the right of the current location.
