Search through an array

I have the following that I insert into an array by splitting them with & so I get the following in the array


RESULT=0  PNREF=sadfsadfas RESPMSG=AAA
AUTHCODE=111111  AVSADDR=Y  AVSZIP=Y  CVV2MATCH=Y  PPREF=0FAfFS33432P  CORRELATIONID=2c234fa97458s  IAVS=N




I want to search through them and find where RESULT=, where PNREF=, where RESPMSG=, etc.
