Replacing Reversed Brackets

[Beasts]

due to my site being RTL, the brackets are reversed when i fetch them from the database. i've been using RegEx to get past the problem but i've discovered another problem. this is the pattern im using now:

 

 

$pattern = "/\)(.+)\(/i";

 

 

this works when there is only one set of inverted brackets within given string. but if the text is like ")a( something )b( another thing" it only corrects the first and last bracket only, leaving the text like "(a( something )b) another thing"
