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;

  }

}

?>
