Regex check for quotes

What regex pattern can be used to check to see if there is a string quote in a string?

example,

"bob said hi" //string 1

and he said "hello" //string 2


i want to make sure that string 1 or string 2 have quotes (opening and closing, together)

thanks

This?

\".+\"

Which'll match ["Hello" world"] - wouldn't a non-greedy match be more appropriate?

\".+?\" (i.e. match ["Hello" world]

I am not ashamed of my avarice.
