MySQLi 的无缓冲查询？

Question

MySQLi 查询是无缓冲的吗？如果没有，是否有办法执行无缓冲查询，就像非 MySQLi mysql_unbuffered_query() 一样？

Answer 1

MindStalker 是对的，但也许最简单的方法是 PHP 手册中显示的方法
http://php .net/manual/en/mysqlinfo.concepts.buffering.php

将 MYSQLI_USE_RESULT 常量作为 resultmode 参数传递，您可以设置 mysqli_query 用作 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

这对我有用

$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();
