change line number 13 with follwing line, comment your if condtion

if (in_array($loc_con1[$j], $loc_con))

Did you analyze your html in a browser after worked script? There are elements "option" with attribute "selected="selected""
Maybe condition "if($loc_con1[$j] == $loc_con[$i])" never don't cause.
