我正试图创建一个基于域扩展更改网站区域设置的函数，但当我尝试将AppModel中的变量值设置为函数时，我遇到了一个错误。我不确定我做错了什么。
仅供参考：$_SERVER['HTTP_HOST']='.de'；
class AppModel extends Model {
//var $locale = 'de_de'; // Example of what I need
var $locale = $this->getLocale();
function getLocale() {
$domain = explode('.', $_SERVER['HTTP_HOST']);
if ($domain[1] == 'de') {
return 'de_de';
} else {
return 'en_gb';
}
}
}
返回错误：

提前谢谢。
错误消息非常清楚地表明：php 无效
您仍然需要编写有效的PHP代码（即使它是cakePHP）！使用合适的IDE会立即列出错误：
var $uses ('App');
应该是
public $uses = array('App');
如文件所示！
如果您仍在PHP4上，则需要"var"而不是"public"
你真的应该开始阅读基本的php书籍，因为你似乎缺乏基本的东西。在类声明中也不能使用动态方法：
var $locale = $this->getLocale();
您需要为此使用构造函数：
public function __construct($id = false, $table = null, $ds = null) {
parent::__construct($id, $table, $ds);
$this->locale = $this->getLocale();
}
