我把PHP代码放在我的文件之上，虽然路径是正确的，但是当我运行它时，它说没有找到对象 [英] I put a PHP code on top of my file, though the path is right but when I run it, it said object not found

问题描述

这是我的代码



文件名是admin2.php，目前在grapesjs文件夹中

<？php require../login/loginheader.php; 
 
需要../login/dbconf.php; 
 $ dbconn = mysqli_connect（$ host，$ username，$ password，$ db_name）; 
 
函数清理（$ str）{
 global $ dbconn; 
 $ str = trim（$ str）; 
 $ str = stripslashes（$ str）; 
 $ str = htmlentities（$ str，ENT_QUOTES）; 
 $ str = mysqli_real_escape_string（$ dbconn，$ str）; 
返回$ str; 
} 
 
 if（isset（$ _SESSION ['username']））{
 $ thisUser = clean（$ _ SESSION ['username']）; 
} 
 
 
 if（isset（$ _ POST ['action']））{
 $ content = mysqli_real_escape_string（$ dbconn，$ _ POST ['content'] ）; 
 $ sql1 =UPDATE`member` SET`content` ='。$ content。'WHERE`username` ='。$ thisUser。'; 
 $ query1 = mysqli_query（$ dbconn，$ sql1）; 
}

和这里我的文件夹里面是什么



grapesjs

> admin2.php

登录

> loginheader.php

> dbconf.php

用户名，

here is my code

the file name is admin2.php, currently in grapesjs folder

<?php require "../login/loginheader.php"; 

require "../login/dbconf.php";
$dbconn = mysqli_connect($host, $username, $password, $db_name);

function clean($str){
    global $dbconn;
    $str = trim($str);
    $str = stripslashes($str);
    $str = htmlentities($str, ENT_QUOTES);
    $str = mysqli_real_escape_string($dbconn, $str);
    return $str;
}

if( isset( $_SESSION['username'])){
  $thisUser = clean($_SESSION['username']);
}


if( isset($_POST['action'])){
    $content = mysqli_real_escape_string($dbconn,$_POST['content']);
    $sql1 = "UPDATE `members` SET `content`= '".$content."' WHERE `username` ='".$thisUser."'";
    $query1 = mysqli_query($dbconn, $sql1);
}

?>

and here whats inside my folder

grapesjs
>admin2.php
login
>loginheader.php
>dbconf.php

What I have tried:

i changed the path to

<?php require "./login/loginheader.php"; 

require "./login/dbconf.php";
$dbconn = mysqli_connect($host, $username, $password, $db_name);

解决方案
