Question

I’m looking for a regex to preg_replace in strings between curly brackets followed by $ symbol in this way:

{$string} //match
{$123string} //match
{string} //no match
{$string123} //match
[$string] //no match

Let’s say you have $string {$Emergento}.

If you want to replace the entire string, then use:

preg_replace('/({\\$.*?})/', $sub, $string); 

If you want to replace $Emergento, then use:

preg_replace('/{(\\$.*?)}/', $sub, $string); 

and if you want to replace just Emergento, then use:

preg_replace('/{\\$(.*?)}/', $sub, $string);
