First thanks all for your solutions. But the problem is in the array B, i have colors such as Neon Pink, Neon Yellow, Neon Green, Neon Purple etc. when using split it splits into Neon one element and Pink one element and so on.
But Neon Pink is a single color. Because each element i am storing in an array and inserting into database. so the single element splits into two. Also i have colors like Translucent Navy, Purple Ice, Blue Ice etc. any ideas. thanks all for your suggestions.
