            return $re;
        } else {
            return false;
        }

Answer 1

After the insert statement you can execute select id.currval from dual . This should give you the latest value. Do note that this will only work only in the current session after you have fetched the nextval and cannot be used by itself.

Answer 2

add the following to your insert SQL query:

returning id into :id

Example:

$query = 'INSERT INTO hist_news (id,headline,reportedon,reportedby,loc,story,more,helperjson,refjson,createdt,createdby) VALUES(id.nextval, :headline, :reportedon, :reportedby , :loc , :story , :more , :helper , :ref , sysdate , :createdby) returning id into :id';

And bind this to your statement

oci_bind_by_name($this->stmt,":ID",$id);

Now $id will have the last inserted ID after oci_execute($this->stmt) is executed;

This method works well with OCI8.
