I need to iterate a loop to every time find the string appearing after a particular string say "if(OLD.", then which PHP function will be helpful for me?

Suppose I have a variable say, $string, according to any select query say "select * friends", Now any of its value contain a string say "how are you Jack?" Now I want to iterate a loop around the above value containing variable to get the varying name of friends after a string "how are you "... Hence I need a function of PHP to accomplish it... Please help
