Access values within an array

Question

I’m having a question to access the variable inside an array, I’m a bit new in the PHP world (only next to the server without HTML) and I need to handle a server response.

I’m not getting basic access to variable

If I try

echo $data[0]->id

returns

Trying to get property of non-object

The print_r second response array

Array

Answer 1

To access the id variable you can do as follows:

echo $data[0]['id'];

This array is multidimencional, that is, to access more "internal" information of the array you can go adding ['kay'] with their respective keys.

You should only use -> to access objects, which is not the case.

Answer 2

As Phelipe said, you can access the array element using the element keys:

$value = $data[0]['id'];

But if you want to treat it as an object, you can also do a cast, it would look like this:

$value = ((object)$data[0])->id;
