Question

我有以下类，它有很多私有变量。

class plantOfTheMonth {

//Declare which centre(s) are being used
private $centre = "";

//Declare the attributes of the current Plant Of The Month
private $name = "";
private $latinName = "";
private $image = "";
private $imageAlt = "";
private $imageLink = "";
private $strapLine = "";
private $description = "";
private $colour = "";
private $centres = "";

//Declare variables for error handling
private $issue = "";
private $issueCode = "";

public function __construct() {

}

public function returnAttributes() {

    $list = ""; //Set an Empty List

    foreach($this as $key => $value) {

        decodeText($value); //decode performs a stripslashes()
        $$key = $value; //Use a variable variable and assign a value to it 
        $list .= "'".$key."', "; //add it to the list for the compress()

    }

    $list .= substr($list, 0, -2); //Take the final ", " off
    return compact($list); //return the list of variables as an array

}
}

我想将所有属性作为变量返回其值，以便我可以预填充表单域。我有一个数据库查询，它填充了所有属性（通过测试证明了这一点）。在我OO之前的日子里，我从数据库中检索信息，将其放入变量中，然后使用compress（）发送和extract（）来获取所有变量。这是否会起作用，就像在我的类中的returnAttributes（）方法一样？

为什么要这么复杂？这是一个代码少得多的例子，它具有所需的行为。

public function returnAttributes()
{
    $list = array(); //Set an Empty List

    foreach(array_keys(get_class_vars(__CLASS__)) as $key)
    {
        $list[$key] = $this->$key;
    }

    return $list;
}

OO PHP将所有私有变量作为变量返回到页面上
