(ii) post some lines of your actual code showing what you expect, and what you actually get. (iii) to know exactly what we're dealing with, var_dump $row and $row2 before you do the strpos, and cut'n'paste the results for us. (iv) also, quote your string subscripts ($row['bands']) -- not vital, but suppresses a constant-lookup and notice for each one, and hence is more efficient. Cheers!
