PHP regex get only first value in between two strings

I have a string that looks like this

aa bcdef123efg hh aa lklmasd456 hh (whitespace and bolding is used for illustration)

If I have 456, I want to find where 456 is and grab everything in between aa and hh.

This is the regex that I was able to come up with so far (?=aa)(.*)456(.*)(?=hh)

However, that doesn't stop at the first occurance of aa it encounters (backwards from the 456 match)

What would be the proper syntax for what I'm trying to achieve.

You can use this lookaround based regex:

aa((?:(?!hh).)*?456(?:(?!hh).)*?)hh
