    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 =)
