I had some problem when to post array data:
When I post the data it will be 2 array:
Array(1)[
[0]=>1
[1]=>2
[2]=>3
]
Array(2)[
[0]=>1
[1]=>
[2]=>3
]
Note that Array2 will be some blank data.
Now I am working until using array_filter(Array2) but the question is can i get the key /data from Array1 match to the not null data from Array2?
Maybe it will be some confusing on question, Sorry to my bad language...
