What if you have an array like this:
Array
(
[0] => Array
(
[0] => 1
[1] => 2
[2] => 2
[3] => 2
[4] => 2
[5] => 4
)
[1] => 4
[2] => 2
[3] => 4
)
And i want to remove the 4, but i don't know 1 and 3. using array_flip
wouldn't work because of my multi-dimensional array. But what if i'm
using array_search? will it return 1 only? will it return 5?
Why in the world you'd architect the array with a value when you need
to unset by value in the first place is beyond me, though...
Sometimes you end up with such arrays, where you need to have
non-unique values first, so you store them in the value, and then you
need to remove some of the non-unique values. But it's a
multi-dimensional array...
