How to get specific field of an associative array without using a loop?

Question

I want to get a specific field of an array but it keeps on sending me error like Undefined index: in or Cannot use object of type stdClass as array in.I'm using codeigniter and this array is from my model and it is returned in my controller. Here is my controller.

  $data['inpatient'] = $this->billing_model->retrieveinpatient();
  echo $data['inpatient']['in'];

Here is the structure of my array:

 Array
 (
  [inpatient] => Array
    (
        [0] => stdClass Object
            (
                [iid] => 1
                [in] => IN
            )
    )

)

Any help?

Look at your structure. The array output is key => value. Your first array has key inpatient. The inpatient value is an array with one key - 0, holding stdClass.

So it must be

echo $data['inpatient'][0]->in;

The problem is that you are trying to access an object with the array dot notation.

Try this:

echo $data['inpatient'][0]->in;

The $data['inpatient'] is indeed an array, so you can use the index notation. In my example, the index is 0. Once you're pointing to the correct index, you'll have a stdClass Object to work with. In order to extract a property of stdClass Object, you can use the object property notation -> to get at the in property.
