PHPMYADMIN LAST_INSERT_ID returns 0

I have problem with LAST_INSERT_ID.

CREATE TABLE for_test(
id_test INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
test_name VARCHAR(30)
);

INSERT INTO for_test (test_name) VALUES ('test1');
INSERT INTO for_test (test_name) VALUES ('test2');

I added successfully two records - yet SELECT LAST_INSERT_ID() still returns 0. (I use InnoDB if that even matters)

Could anyone tell me what I'm doing wrong?

CREATE TABLE for_test(
id_test INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
test_name VARCHAR(30)
);

INSERT INTO for_test (test_name) VALUES ('test1');
INSERT INTO for_test (test_name) VALUES ('test2');
SELECT LAST_INSERT_ID();

Note: it's working with Engine - InnoDB in phpMyAdmin. if you still have same problem, will you please send error snapshot, so that we can track exact issue.

Hope this will help you!!

No other query after insert and they both should execute together. Be careful that. Also if you can not handle it you can use 

SELECT id FROM for_test ORDER BY id DESC LIMIT 1;

and you can read this manual

you should try mysqli example

$sql = "INSERT INTO user (firstname, lastname, email)
VALUES ('test', 'test', '[email protected]')";

if ($conn->query($sql) === TRUE) {
    $last_id = $conn->insert_id;
    echo "New record created successfully. Last inserted ID is: " . $last_id;
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}
