OO PHP 将所有私有变量作为页面上的变量返回
OO PHP returning all private variables as variables on page
问:
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及其值返回,以便我可以预填充表单字段。我有一个数据库查询,它填充了所有属性(经测试证明其工作原理)。在我之前的 OO 时代,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() 获取所有变量。这是否有效,就像我类中的 returnAttributes() 方法一样?

为什么要让它变得如此复杂?下面是一个示例,其中的代码要少得多,但具有所需的行为。
public function returnAttributes()
{
$list = array(); //Set an Empty List
foreach(array_keys(get_class_vars(__CLASS__)) as $key)
{
$list[$key] = $this->$key;
}
return $list;
}
