PHP Regex Dealing With Parenthesis -

-

As far as I understand, regex is tried to match all the points mentioned in parentheses.

like 

  & lt; P & gt; & Lt (*.); / P & gt;

How to distinguish between how and how the braces mentioned in regular expressions within a large regular expressions. 

  (hello), (how)

In the above example, we need to match the bracket, but if the parentheses near RACF [first example , Then how will it be differentiated?

thanks

if you literally go to () If you want to match, you can avoid most of these regex engines like: \ (, \) .
