PHP MySQL reads data

Example (PDO)

"; echo "IdFirstnameLastnameEmailReg date"; class TableRows extends RecursiveIteratorIterator { function __construct($it) { parent::__construct($it, self::LEAVES_ONLY); } function current() { return "" .parent::current(). ""; } function beginChildren() { echo ""; } function endChildren() { echo "" . "\n"; } } $servername = "localhost"; $username = "username"; $password = "password"; $dbname = "myDBPDO"; try { $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password); $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $conn->prepare("SELECT * FROM MyGuests"); $stmt->execute(); // 设置结果集为关联数组 $result = $stmt->setFetchMode(PDO::FETCH_ASSOC); foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as$k=>$v) { echo $v; } $dsn = null; } catch(PDOException $e) { echo "Error: " . $e->getMessage(); } $conn = null; echo ""; ?>
