I was recieving the same error when I was tring to call an object element by using another objects return value like;

$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes

$this->array2->$this->array1->country;// Error line

The above code was throwing the error and I tried many ways to fix it like; calling this part $this->array1->country in another function as return value, (string), taking it into quotations etc. I couldn't even find the solution on the web then i realised that the solution was very simple. All you have to do it wrap it with curly brackets and that allows you to target an object with another object's element value. like;

$this->array1 = a json table which returns country codes of the ip
$this->array2 = a json table which returns languages of the country codes

$this->array2->{$this->array1->country};

If anyone facing the same and couldn't find the answer, I hope this can help because i spend a night for this simple solution =)

data is indeed an array  but it s made up of objects   Convert its content to array before creating it    data   array    foreach   results as  result        result- gt filed1    some modification       result- gt filed2    some modification2       data      array  result        or first convert it and then change its properties using      an array syntax  it s up to you   Excel  create

This is easy all you need to do is something like this Grab your contents like this     result- gt get filed1     some modification      result- gt get filed2     some modification2

You might need to change your object to an array first  I dont know what export does  but I assume its expecting an array   You can either use  get object vars    Or if its a simple object  you can just typecast it    arr     array   Object
