Question

我正在使用Cpanel来开发我的应用程序。它给出了错误

Fatal error: Call to a member function set_charset() on a non-object in /home/restaur  /public_html/restaurant/includes/connect_database.php on line 3

当我访问“www.yyyyy.com/filename /”

时

这是我的connect_database脚本

<?php 
include($_SERVER['DOCUMENT_ROOT'].'/YOUR_FOLDER/variables/variables.php'); 
$connect->set_charset('utf8');  
?>

我的close_database脚本

<?php
include($_SERVER['DOCUMENT_ROOT'].'/YOUR_FOLDER/variables/variables.php');
$connect->close();
?>

我的变量脚本

<?php
// database configuration
$host ="db_host_name";
$user ="db_username";
$pass ="db_pasword";
$database = "database_name";
$connect = new mysqli($host, $user, $pass,$database) or die("Error :       ".mysql_error());?>

Answer 1

它应该像

$host ="db_host_name";
$user ="db_username";
$pass ="db_pasword";
$database = "database_name";

// variables.php
$connect = new mysqli($host, $user, $pass, $database);

/* check connection */
if ($connect->connect_errno) {
    printf("Connect failed: %s\n", $connect->connect_error);
    exit();
}

现在在connect_database.php

// Make sure your included path is correct
include($_SERVER['DOCUMENT_ROOT'].'/YOUR_FOLDER/variables/variables.php'); 
global $connect;

$connect->set_charset('utf8');

这将有助于您深入了解global

Answer 2

我遇到了这个问题，我遇到了编码问题但添加了

$connect->set_charset('utf8');

在

之后

（我的变量实际上是$conn->set_charset('utf8');）

$conn = new mysqli($servername, $username, $password, $dbname);

它工作得很漂亮。

致命错误：调用成员函数set_charset（）
