Question

I want to create a method for my class that deleting one record, here is the source:

/* Delete One Record
 * in @param (string) $tbl - name of the table
 * in @param (int) $idn - id of record
 * @return (int) - identifier of removed record
 */
public function DelOne($tbl,(int)$idn)
{

    if ($result = $this->pdo->prepare("DELETE FROM `".$tbl."` WHERE `id`=:idn"))
    {

        $result->bindValue(":idn",$idn,PDO::PARAM_INT);

        $result->execute();

    }

}

And I want that this function returns me an identifier of just removed record instead of standart TRUE/FALSE combination.

Answer 1

Add return $idn in the function?

public function DelOne($tbl,(int)$idn)
{

    if ($result = $this->pdo->prepare("DELETE FROM `".$tbl."` WHERE `id`=:idn"))
    {

        $result->bindValue(":idn",$idn,PDO::PARAM_INT);

        // if all is well, return $idn
        if($result->execute()) return $idn;

    }

    // if we are here, something was wrong
    return false;

}
