Integrate embedded CSV file - PHP

I am trying to integrate a embedded CSV file via PHP using a form search.

My CSV looks like this:

ACCTNO        PRCLID    NOTICES
00109033-01   234962    2056, 3005, 1033
00104120-04   200921    2006, 3002, 3004, 2056, 1033
00170172-01   299573    2056, 3001, 3003, 3004, 1033
00106284-02   208709    1026, 2056, 3004, 1033
00150372-01   222376    2056, 3001, 2006, 1033

Basically I am trying to have a search box where the user enters 00109033-01, and a the three divs that correspond to 2056, 3005 and 1033 (from the 'NOTICES' column) are presented. If the user searched for 00104120-04 the five divs that correspond to 2006, 3002, 3004, 2056, 1033 (from the 'NOTICES' column) are presented.

I will have corresponding divs for each of the 'NOTICE' codes, some relate to an account, others don't.

I know how to embed CSV data but I am struggling to workout the interrogation part and presenting the corresponding divs.

Any hints, code help or even just the right terminology for what I am trying to achieve would be a great help.
