However, mysqlnd sets the error in conn property which means mysqli will not throw it. Test script: --------------- <?php mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); $mysqli = new mysqli('localhost', 'user', 'password', 'test'); $mysqli->set_charset('utf8mb4'); // always set the charset $statement = $mysqli->prepare("SELECT b FROM a"); $statement->execute(); $statement->bind_result($name); $statement->fetch(); $statement->store_result(); var_dump($mysqli->error, $statement->error); echo $statement->num_rows(); Expected result: ---------------- Fatal error: Uncaught mysqli_sql_exception: Commands out of sync; you can't run this command now Actual result: -------------- string(52) "Commands out of sync; you can't run this command now" string(0) "" 0 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80837&edit=1
