使用 MySQLi 進行無緩沖查詢？

Question

MySQLi 查詢是否無緩沖？ 如果沒有，有沒有辦法像非 MySQLi mysql_unbuffered_query()那樣進行無緩沖查詢？

Answer 1

MindStalker 是對的，但也許最簡單的方法是 PHP 手冊中顯示的方法
http://php.net/manual/en/mysqlinfo.concepts.buffering.php

傳遞 MYSQLI_USE_RESULT 常量作為resultmode參數，您可以將mysqli_query設置為mysql_unbuffered_query

<?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();
?>

Answer 2

mysqli_real_query() 后跟 mysqli_use_result()

Answer 3

這個對我有用

$uresult = $mysqli_new->query("INSERT INTO world (username, userid, points, price, br, admin) 
VALUES ('$word[username]',$word[userid], $points, 0, 0, '$word[adminname]')", MYSQLI_USE_RESULT);
$uresult = $mysqli_new->query("SELECT username FROM world WHERE userid='$word[userid]'", MYSQLI_USE_RESULT);
if ($uresult) 
{
    while ($row = $uresult->fetch_assoc()) 
    {
       echo "uresult: ".$row['username'] . PHP_EOL;
    }
}
$uresult->close();
