php add array to array without key

Question

I have an API that I need to write to that expects

$foo = array(
  'tags[]' => array('one','two','three','four')
);

My array looks like this

Array
(
    [0] => one
    [1] =>  two
    [2] =>  three
    [3] =>  four
    [4] =>  five
    [5] =>  six
)

I've tried adding the array

$foo = array(
  'tags[]' => array($arr)
);

But this prints 'Array' once in the database. How do I add the values from $arr to the tags[]?

If you see Array, then you are converting your array to a string. You can't store an array in a database, only strings. Maybe you want to json_encode($arr)? — gen_Eric

Looks like you've got an extra ' and you unintentionally stringified the array($arr) that you pass, which then gets inserted. — brbcoding

Use json_encode on array to save on database, and json_decode to revert from db. — Maykonn

Your tags[] array is one level too deep. It should be:

$foo = array(
  'tags[]' => $arr
);

Note how $arr is not wrapped in array().

If you don't remove the array() then it looks like:

$foo = array(
  'tags[]' => array(
      array('one', 'two', 'three')
  )
);

Thanks for your reply, unfortunately this give me {"messages":{"tags":["This value is not valid.","This value is not valid.","This value is not valid.","This value is not valid.","This value is not valid."]},"error":"invalid"}

You will have to look at the API source code or documentation to find out the problem. Either it wants a different format or the content of the tags you're passing is invalid according to the API.

I know array('one','two','three','four') work. just that I doesn't like the key value of the array, it just expects value.

array('one','two','three','four') is same as array('0'=>'one', '1'=>'two', '2'=>'three', '3'=>'four', '4'=>'five', '5'=>'six')
