Issue: https://github.com/php/php-src/issues/8746 Author: jtuta ### Description The following code: ```php <?php $dbh = new PDO('mysql:host=mysql;dbname=database', 'user', 'pass'); $dbh->prepare("CREATE TABLE Datatable (id int NOT NULL, value varchar(45) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci NOT NULL) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci; ALTER TABLE Datatable ADD PRIMARY KEY (id), ADD UNIQUE KEY id (id); ALTER TABLE Datatable MODIFY id int NOT NULL AUTO_INCREMENT;")->execute(); $stmt = $dbh->prepare("insert into Datatable (value, id) values (?, ?)"); $stmt->execute( array('test', -1)); var_dump( $dbh->lastInsertId(), $dbh->query("SELECT * FROM Datatable")->fetch() ); ``` Resulted in this output: ``` string(20) "18446744073709551615" array(4) { ["id"]=> int(-1) [0]=> int(-1) ["value"]=> string(4) "test" [1]=> string(4) "test" } ``` But I expected this output instead: ``` string(20) "-1" array(4) { ["id"]=> int(-1) [0]=> int(-1) ["value"]=> string(4) "test" [1]=> string(4) "test" } ``` Example has been run in docker image: - php:8.1-fpm - mysql image (if relevant) mysql:8.0.27 I ### PHP Version PHP 8.1.7 ### Operating System Ubuntu 22.04
