Php variable representation

Question

I have this code

if($pdo instanceof PDO){
    $this->last = 'lastInsertId'; 
}
else{
     $this->last = 'insert_id'; 
}

When i do the insert query in the datebase, how can i get the last inserted ID. I tried like this

$this->db->{$this->last};

But it did not work.

Thanks for the help in advance.

You need to provide full code, it is not clear which class does insert operation and which tries to get the id. If $this->db is $pdo, then $this->db->last should be used, otherwise, $this->last only — Amit

no i assign instance of another DB class which uses PDO but returns instance of itself. — Lachezar Raychev

lastInsertId is a method, therefore you should call it as a method, not as a property/field.

$this->db->{$this->last}();

Try call_user_func(Array($this->db,$this->last))
