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; }}?>
