thanks in advance answer

do this:

$replaced = preg_replace('~{([^}]*)}~', '$$1', $yourstring);

on the demo, see substitutions @ bottom.

{ matches opening brace
} matches closing brace
in ([^}]*), parentheses captures group 1 [^}]*... [^}] negative character class means 1 char not closing brace, , * quantifier means 0 or more times
$$1 replaces match literal $ , content of capture group ($1)
