在类中使用全局数组
我的目标是从另一个 PHP 文件中定义的全局数组中检索一些数据。我的代码在“database.php”文件内运行，我想使用的数组位于“config.php”文件内。
我的代码如下：
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();
}
// ...
};
给出的错误是：
解析错误：语法错误，意外 '}'，期待 ']' C:...\database.php 第 16 行
我无法弄清楚我在这里做错了什么。
请帮我修复这个错误。
（注：PHP版本为5.3.0）
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)

所有 4 行上的
["DATABASE"}=["DATABASE"]。["DATABASE"}=["DATABASE"]on all 4 lines.你没有正确配对你的括号
应该是
You aren't pairing your brackets properly
Should be
此后第 16 行和第 3 行出现拼写错误。
["DATABASE"} = ["DATABASE"]应该是`["DATABASE"] = ["DATABASE"]You have typo error on line 16 and 3 after that.
["DATABASE"} = ["DATABASE"]should be `["DATABASE"] = ["DATABASE"]
