It's rather easy:
for ($i=0; $i<count($arr); $i++) {
if ($arr[$i][0] == $new_array[0]) {
$arr[$i][1] += $new_array[1];
break; // Optional - means the first "orange" found will be

Small correction:
for ($i=0; $i<count($arr); $i++)
{
if ($arr[$i][0] == $new_value [0])
{
$arr[$i][1] += $new_value [1];
break; // Optional - means the first "orange" found will be
// updated only
}
}

But, I'm not sure as to why you (Brian) would want to do that anyway.
