在类中使用全局数组 [英] Using a global array inside a class

问题描述

我的目的是从另一个PHP文件中定义的全局数组中检索一些数据。我的代码运行在database.php文件中，我想要使用的数组在config.php文件中。

我的代码如下： p>

config.php

  $ CONFIG = array（）; 
 // ... 
 $ CONFIG [DATABASE] = array（）; 
 $ CONFIG [DATABASE] [USERNAME] =用户; 
 $ CONFIG [DATABASE] [PASSWORD] =通过; 
 $ CONFIG [DATABASE] [HOSTNAME] =127.0.0.1; 
 $ CONFIG [DATABASE] [DATABASE] =我的_db; 
 // ... 
  

database.php p>

  require（'config.php'）; 
 
类数据库
 {
 protected $ m_Link; 
 private $ m_User; 
 private $ m_Pass; 
 private $ m_Host; 
 private $ m_Data; 
 private $ m_bConnected; 
 
 public function __construct（）
 {
 global $ CONFIG; 
 $ this-> m_User = $ CONFIG [DATABASE} [USERNAME]; // Line＃16 
 $ this-> m_Pass = $ CONFIG [DATABASE} [PASSWORD]; 
 $ this-> m_Host = $ CONFIG [DATABASE} [HOSTNAME]; 
 $ this-> m_Data = $ CONFIG [DATABASE} [DATABASE]; 
 $ this-> m_bConnected = false; 
 $ this-> Connect（）; 
} 
 
 // ... 
}; 
  

出现的错误是：

解析错误：语法错误，意外
'}'，期望']'在
C：... \database.php在第16行

我无法弄清楚我在这里做错了什么。

请帮我修复错误。

（注意：PHP版本为5.3.0）

解决方案

<所有4行中的

[DATABASE} = [DATABASE] $ b

My aim is to retrieve some data from a global array which is defined in another PHP file. My code is running inside "database.php" file and the array I want to use is inside "config.php" file.

My code is as below:

config.php

$CONFIG = array();
// ...
$CONFIG["DATABASE"] = array();
$CONFIG["DATABASE"]["USERNAME"] = "user";
$CONFIG["DATABASE"]["PASSWORD"] = "pass";
$CONFIG["DATABASE"]["HOSTNAME"] = "127.0.0.1";
$CONFIG["DATABASE"]["DATABASE"] = "my_db";
// ...

database.php

require('config.php');

class Database
{
    protected   $m_Link;
    private     $m_User;
    private     $m_Pass;
    private     $m_Host;
    private     $m_Data;
    private     $m_bConnected;

    public function __construct()
    {
        global $CONFIG;
        $this->m_User = $CONFIG["DATABASE"}["USERNAME"]; // Line #16
        $this->m_Pass = $CONFIG["DATABASE"}["PASSWORD"];
        $this->m_Host = $CONFIG["DATABASE"}["HOSTNAME"];
        $this->m_Data = $CONFIG["DATABASE"}["DATABASE"];
        $this->m_bConnected = false;
        $this->Connect();
    }

    // ...
};

The error given is:

Parse error: syntax error, unexpected '}', expecting ']' in C:...\database.php on line 16

I couldn't figure out what I'm doing wrong here.

Please help me fix this error.

(Note: PHP version is 5.3.0)

解决方案

["DATABASE"} = ["DATABASE"] on all 4 lines.
