错误是：致命错误：调用未定义的函数Connect_DB（）第12行的C：\ wamp \ www \ movie \ movies.php

config.php：

<?php
//error_reporting(0);

class Connection{
    private $host = "localhost";
    private $username = "root";
    private $password = "";
    private $db = "movies";
    private $connect;
    private $q;

    function Conn(){
        $this->connect = @mysql_connect($this->host, $this->username, $this->password);
        return $this->connect;
    }

    function Select(){
        mysql_unbuffered_query('SET NAMES utf8');
        return mysql_select_db($this->db);
    }

    function Query($sql){
        $this->q = mysql_query($sql);
        return $this->q;
    }

    function Rows(){
        return mysql_num_rows($this->q);
    }

    function Object(){
        return mysql_fetch_object($this->q);
    }
}
?>

movies.php：

<?php
class Movies{
    function Connect_DB(){
        $data = new Connection;
        if(!($data->Conn())) header("Location: 404.php");
        if(!($data->Select())) header("Location: 404.php");
        return $data;
    }
    function getImdb(){
        $q = "SELECT * FROM top250";
        $data = Connect_DB();
        $ch = $data->Query($q);
        if($ch){
            $i=0;
            while($r = $data->Object()){
                $result["name"][$i] = $r->name;
                $result["genre"][$i] = $r->genre;
                $result["imdb"][$i] = $r->imdb;
                $result["year"][$i] = $r->year;
                $result["releaseDate"][$i] = $r->releaseDate;
                $result["country"][$i] = $r->country;
                $result["imgPath"][$i] = $r->imgPath;
                $i++;
            }//while
            return $q;
        }else{
            $result = false;
            return $result;
        }//else
    }//getImdb
}
?>

这是html文件：

<?php
require "config.php";
require "movies.php";
$imdb = new Movies;
$result = $imdb->getImdb();

?>
<!DOCTYPE HTML>
<html>
    <head>
.....

我找不到错误的位置？我有2个类（config.php和movies.php）Config.php有mysql连接设置，电影从mysql获取一个表，html文件包含2个文件和show table。有人能帮助我吗？

您没有正确调用CONNECT_DB。在一个类中，当你想调用另一个方法时，我们使用$ this-＆gt; method（）。因此，将行$data = Connect_DB();更改为$data = $this->Connect_DB();
