为什么我的服务器出问题？ [英] Why is my server giving problems?

问题描述

我已经在wamp服务器设置端创建了一个文件夹android_connect，并在那里上传了我的php文件。你可以在下面的错误中看到文件路径..文件是：



db_config.php

 <？php  
 define（'  DB_USER'，  root）; 
 define（'  DB_PASSWORD'，  vikrant）; 
 define（'  DB_DATABASE'，  sys）; 
 define（'  DB_SERVER'， 本地实例wampmysqld64）; 
 ？> ; 

db_connect.php

 <？php  
  class  DB_CONNECT {
 function _construct（）{
 $ this-> connect（）; 
} 
函数_destruct（）{
 $ this-> close（）; 
} 
函数connect（）{
 require_once_DIR _。'  / dbconfig.php' ; 
 $ con = mysql_connect（DB_SERVER，DB_USER，DB_PASSWORD）或 die（mysql_error（））; 
 $ db = mysql_select_db（DB_DATABASE）或 die（mysql_error（））或 die（mysql_error） （））; 
  return   $ con ; 
} 
函数close（）{
 mysql_close（）; 
} 
} 
 ？> ; 

get_all_products.php

  <？php  
 $ response = array（）; 
 require_once_DIR _。'  / db_connect.php'; 
 $ db = new DB_CONNECT（）; 
 $ result = mysql_querry（  SELECT * FROM users）或 die（mysql_error（））; 
 if（mysql_num_rows（$ result）> 0）{
 $ response [  products ] =阵列（）; 
 while（$ row = mysql_fetch_array（$ result））{
 $ product = array（）; 
 $ product [  pid] = $ row [  pid]; 
 $ product [  name] = $ row [  name]; 
 $ product [  price] = $ row [  price]; 
 $ product [  description] = $ row [  description]; 
 $ product [  created_at] = $ row [  created_at]; 
 $ product [  updated_at] = $ row [  updated_at]; 
 array_push（$ response [  products]，$ product）; 
} 
 $ response [  success] = 1; 
  echo  json_encode（$ response）; 
} else {
 $ response [  success] = 0; 
 $ response [  message] =   找不到产品。; 
  echo  json_encode（$ response）; 
} 
 ？> ; 

这是错误的：

不推荐使用：mysql_query（）：不推荐使用mysql扩展，将来会删除它：在C：\ wamp64中使用mysqli或PDO第5行的\\\android_connect\get_all_products.php 
 
警告：mysql_query（）：在C：\ wamp64 \\中拒绝用户''@ localhost'（使用密码：NO）第5行上的\\android_connect\get_all_products.php 
 
警告：mysql_query（）：无法在C：\ wamp64 \ www; \\ android_connect \中建立指向服务器的链接第5行的get_all_products.php 

这些是我尝试上传的众多文件中的一部分。请提前帮助并谢谢。



我的尝试：



尝试重写代码并重新上传..

解决方案

this-> connect（）;
}
函数_destruct（）{

this-> close（）;
}
函数connect（）{
require_once_DIR _。' / dbconfig.php' ;

con = mysql_connect（DB_SERVER，DB_USER，DB_PASSWORD）或 die（mysql_error（））;

I have created a folder inside the wamp server setup end as "android_connect" and have uploaded my php files there. you can see the file path if you want in the errors below.. the files are :

db_config.php

<?php
define('DB_USER',"root");
define('DB_PASSWORD',"vikrant");
define('DB_DATABASE',"sys");
define('DB_SERVER',"Local instance wampmysqld64");
?>;

db_connect.php

<?php
class DB_CONNECT{
	function _construct(){
		$this->connect();
	}
	function _destruct(){
		$this->close();
	}
	function connect(){
		require_once_DIR_.'/dbconfig.php';
		$con=mysql_connect(DB_SERVER, DB_USER, DB_PASSWORD) or die(mysql_error());
		$db=mysql_select_db(DB_DATABASE) or die(mysql_error()) or die(mysql_error());
		return $con;
	}
	function close(){
		mysql_close();
	}
}
?>;

get_all_products.php

<?php
$response=array();
require_once_DIR_.'/db_connect.php';
$db=new DB_CONNECT();
$result=mysql_querry("SELECT * FROM users") or die(mysql_error());
if(mysql_num_rows($result)>0){
	$response["products"]=array();
	while($row=mysql_fetch_array($result)){
		$product=array();
		$product["pid"]=$row["pid"];
		$product["name"]=$row["name"];
		$product["price"]=$row["price"];
		$product["description"]=$row["description"];
		$product["created_at"]=$row["created_at"];
		$product["updated_at"]=$row["updated_at"];
		array_push($response["products"],$product);
	}
	$response["success"]=1;
	echo json_encode($response);
}else{
	$response["success"]=0;
	$response["message"]="No Product Found.";
	echo json_encode($response);
}
?>;

which is giving errors:

Deprecated: mysql_query(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in C:\wamp64\www\android_connect\get_all_products.php on line 5

Warning: mysql_query(): Access denied for user ''@'localhost' (using password: NO) in C:\wamp64\www\android_connect\get_all_products.php on line 5

Warning: mysql_query(): A link to the server could not be established in C:\wamp64\www\android_connect\get_all_products.php on line 5

These are some of many files i have tried uploading. Please help and thank you in advance.

What I have tried:

Tried rewritng the code and reuploading it..

解决方案

this->connect(); } function _destruct(){

this->close(); } function connect(){ require_once_DIR_.'/dbconfig.php';

con=mysql_connect(DB_SERVER, DB_USER, DB_PASSWORD) or die(mysql_error());
