选择随机项从对象

Question

我有一个ini文件是这样的：

[hints] 
menu.0 = "Hint: Dropping a element on parent element will move the selected element at the end of list!" 
menu.1 = "Hint: Use Menu elements to beautify your navigator!" 
menu.2 = "Hint: Pages in red means they are draft pages. Adding them to your menu means that your visitors can not see the page!" 

和阅读使用Zend_Config_Ini的ini文件：

self::$hints = new Zend_Config_Ini(APPLICATION_PATH . '/configs/hints.ini', 
             'hints'); 

上var_dump(self::$hints->menu);输出是：

object(Zend_Config)[63] 
    protected '_allowModifications' => boolean false 
    protected '_index' => int 0 
    protected '_count' => int 3 
    protected '_data' => 
    array (size=3) 
     0 => string 'Hint: Dropping a element on parent element will move the selected element at the end of list!' (length=93) 
     1 => string 'Hint: Use Menu elements to beautify your navigator!' (length=51) 
     2 => string 'Hint: Pages in red means they are draft pages. Adding them to your menu means that your visitors can not see the page!' (length=118) 
    protected '_skipNextIteration' => null 
    protected '_loadedSection' => null 
    protected '_extends' => 
    array (size=0) 
     empty 
    protected '_loadFileErrorStr' => null 

我需要帮助，随机从该对象中挑选一个项目并显示它。

这个PHP函数可以对您有用：

array_rand(); 

参考：array_rand() in PHP.net

由于它是一个对象，你可以事先做：如建议在https://stackoverflow.com/a/1897695/2228023

$arr = (array)$object;
