mysql

mysql_connect($db_host, $db_user, $db_password); mysql_select_db($dn_name); $result = mysql_query("SELECT `name` FROM `users` WHERE `location` = ‘$location‘"); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { echo $row[‘name‘]; } mysql_free_result($result);

mysqli

$mysqli = new mysqli($db_host, $db_user, $db_password, $db_name); $sql = "INSERT INTO `users` (id, name, gender, location) VALUES (?, ?, ?, ?)"; $stmt = $mysqli->prepare($sql); $stmt->bind_param(‘dsss‘, $source_id, $source_name, $source_gender, $source_location);//四個參數 所以是dsss整形\字串 $stmt->execute(); $stmt->bind_result($id, $name, $gender, $location); while ($stmt->fetch()) { echo $id . $name . $gender . $location; } $stmt->close(); $mysqli->close();

pdo

$dsn = "mysql:host=$db_host;dbname=$db_name"; $dbh = new PDO($dsn, $db_user, $db_password); $sql = "SELECT `name`, `location` FROM `users` WHERE `location` = ? , `name` = ?"; $sth = $dbh->prepare($sql); $sth->execute(array($location, $name)); $result = $sth->fetch(PDO::FETCH_OBJ); echo $result->name . $result->location; $dbh = NULL;
