php如何执行非缓冲查询API

对于PHP的缓冲模式查询大家都知道，下面列举的例子是如何执行非缓冲查询API。

非缓冲查询方法一: **mysqli**

    <?php
    $mysqli = new mysqli("localhost", "my_user", "my_password", "world");
    $uresult = $mysqli->query("SELECT Name FROM City", MYSQLI_USE_RESULT);

    if ($uresult) {
      while ($row = $uresult->fetch_assoc()) {
        echo $row['Name'] . PHP_EOL;
      }
    }
    $uresult->close();
    ?>

非缓冲查询方法二:** pdo_mysql**

    <?php
    $pdo = new PDO("mysql:host=localhost;dbname=world", 'my_user', 'my_pass');
    $pdo->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, false);

    $uresult = $pdo->query("SELECT Name FROM City");
    if ($uresult) {
      while ($row = $uresult->fetch(PDO::FETCH_ASSOC)) {
        echo $row['Name'] . PHP_EOL;
      }
    }
    ?>

非缓冲查询方法三: mysql

    <?php
    $conn = mysql_connect("localhost", "my_user", "my_pass");
    $db  = mysql_select_db("world");

    $uresult = mysql_unbuffered_query("SELECT Name FROM City");
    if ($uresult) {
      while ($row = mysql_fetch_assoc($uresult)) {
        echo $row['Name'] . PHP_EOL;
      }
    }
    ?>
