Question

I have a comma separated string which i explode into an array. If the array is of un-known length and i want to make it into a key value pair array where each element in the array has the same key, how do i do this? i’m assuming i’d have to use array_combine? can anyone give me an example using the array bellow? :

for instance:

array([0]=>zebra, [1]=>cow, [2]=>dog, [3]=>monkey, [4]=>ape)

into:

array([animal]=>zebra, [animal]=>cow, [animal]=>dog, [animal]=>monkey, [animal]=>ape)

Answer 1

You can’t use the same key for each element in your array. You need a unique identifier to access the value of the array. When you use animal for all, what value should be used? What you can do is to make a 2 dimensional array that you have an array inside an array:

array(
    [animals] => array(
        [0]=>zebra, [1]=>cow, [2]=>dog, [3]=>monkey, [4]=>ape
    )
) 

this can be used with $array['animals'][0]

But still you need numbers or unique identifiers to access the values of the array.
