Question

I have an array contain this data

Array
    (
    [id] => Array
        (
            [0] => 1
            [1] => 10
            [2] => 4
        )

    [age] => Array
        (
            [0] => 1
            [1] => 1
            [2] => 2
        )
)

Now I want to remove duplicates from the [‘age’] and leave the first one in tact.

So this would return

Array
    (
    [id] => Array
        (
            [0] => 1
            [2] => 4
        )

    [age] => Array
        (
            [0] => 1
            [2] => 2
        ) 
)

Any ideas? Or is there a function already in place to do this?

Answer 1

Like Gordon said, you’d need a custom function to make the relationship but you can use http://php.net/manual/en/function.array-unique.php ?

Wouldn’t it be better to have the keys of the age array the corresponding values of the id array?
