在php 5.3中使用ucfirst（）函數返回一個解析錯誤

Question

我想在我的codeigniter控制器中添加一個ucfirst（）函數，所以我會找回第一個大寫字母的字符串。在...第7行（在我的ucfirst是行）

;語法錯誤，意外「（」，希望「」或‘’：出於某種原因，我不斷收到一個解析錯誤：

解析錯誤。

試圖改變ucfirst（）來ucfirst（用strtolower（$數據庫））或ucwords（$數據庫）返回相同的結果

我的代碼是：

defined('BASEPATH') OR exit('No direct script access allowed'); 

class Somecontroller extends CI_Controller { 
    private $database = "some_database"; 
    private $model = ucfirst($this->database)."_model"; 
    ... 
} 

Answer 1

從php doc

declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.

你應該初始化$model財產類的構造函數

public function __construct() 
{ 
    // I guess you'll need to call parent constructor as well 
    parent::__construct(); 
    $this->model = ucfirst($this->database) . '_model'; 
} 

Answer 2

您應該使用這 - $>數據庫，並在構造函數分配

喜歡的東西：

function __construct() 
{ 
    $this->model = ucfirst($this->database) . "whatEver"; 
}
