Array comparison

hi all,

Actually, i have an array this elements.

("james\tbond\t234235322\n");

("john\tpatel\t234523447\n");

("andrew\thudson\t899940987\n");

("andrew\thudson\t899940987\n");

I would like to compare the entry of an array by SSN which is last field.

Can anybody give me an idea how to do that?
