PHP中的正则表达式-换行符后括号中的单词

Question

Peter (Anna, Tom, Bill)

should look like this:

Peter 
Anna,
Tom,
Bill

Ok, first part, I find text in brackets using preg_grep(). What are functions to extract text from something keeping the old one?

Answer 1

preg_replace should do the trick :

$str = 'Peter (Anna, Tom, Bill)';
echo preg_replace('/\((.*?)\).*/','\\1',$str);

Answer 2

Try this code :-

 $userinfo = "Peter (Anna, Tom, Bill)";
 preg_match_all ("/[A-z]+/", $userinfo, $pat_array);
 echo implode(',',$pat_array[0]);
