Using Prepared Statement, how I return the id of the inserted row?

Question

I want retrieve the id of a inserted row in the database, but I don't know how to do this.

I tried to return using the SQL clause RETURNING id, but not works.

How I can return the id after the insertion of a row?

Answer 1

After calling the execute() method on the Prepared Statement, the id of the insert row will be in the insert_id attribute.

$pstm->execute();
$pstm->insert_id;
