Question

I’m using Zend Framework and MySql to create my web-application. My SQL-code is the following at the moment:

public static function newTestResult($testId, $accountId, $score, $deviation, $averageTime)
    {
        try
        {
            $db = self::conn();
            $statement = "INSERT INTO test_results(test_id, test_person_id, score, standard_deviation, average_answer_time, created_at)
                                        VALUES(" . $testId . ", " . $accountId . ", " . $score . ", " . $deviation . ", " . $averageTime . ", NOW())";
            $db->query($statement);
            $db->closeConnection();
        }
        catch(Zend_Db_Exception $e)
        {
            error_log($e->getMessage());
        }
    }

Now what I’m asking is: How can I get the just inserted row to a variable in PHP? I would want to get my hands on the id-value what MySql is creating automatically for the row.

Here is my table code:

CREATE TABLE test_results(
id int UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
test_id int UNSIGNED NOT NULL,
test_person_id int UNSIGNED NOT NULL,
score float UNSIGNED NOT NULL,
standard_deviation float UNSIGNED NOT NULL,
average_answer_time float UNSIGNED NOT NULL, 
removed boolean NOT NULL DEFAULT 0,
created_at datetime) CHARACTER SET utf8 COLLATE utf8_general_ci;

Answer 1

This should give you the last insert id from the last query made.

$db->lastInsertId()
