Question

我正在尝试在php中创建一个日历类，并且在返回定义为public的类变量时遇到问题。

以下是我班级的代码

<?php 

class CalendarClass {

// property declaration

public $months = array();
public $year;
public $month;
public $day;
public $fourYear;
public $monthFirst;
public $monthMax;
public $monthVal;

private $data = array();

//My set functions

function __construct() {
    $year = date("y");;
    $month = date("n");;
    $day = date("j");;
    $fourYear = date("Y");
    $this->setDate($year, $month, $day, $fourYear);
    echo $fourYear; // echos 2012
}

//I'm not entirely sure if these 2 are set up correctly
//From what I read these are automatically called when
//you set or get variables.
public function __set($dt, $vl) {
    $this->data[$dt] = $vl;
}

public function __get($dt) {
    return $this->data[$dt];
}


//Sets the date and all other variables accordingly
//Must have in this order
//2 digit year, 1/2 digit month and day (ex: 1, 12), 4 digit year 
public function setDate($y, $m, $d, $fourY){
    $year = $y;
    $month = $m;
    $day = $d;
    $fourYear = $fourY; 

    if($day == -1){
        $month = $month - 1;
        if($month == -1){
            $month = 11;
            $fourYear--;
            $year = substr($fourYear, -2);
        }
    }elseif($day > $this->monthMax){
        $month = $month + 1;
        if($month == 12){

    ?>

这是使用该类的代码

    include_once("f_calendar.php"); 

    $thisMonth = new CalendarClass;

    $nextMonth = new CalendarClass;

    $prevMonth = new CalendarClass;

    $y = $thisMonth->getYear();

    $m = $thisMonth->getMonth();

    $d = $thisMonth->getDay();

    $fY = $thisMonth->getFourYear();

    $thisMonth->setDate($y, $m, $d, $fY);

    $nextMonth->setDate($y, $m + 1, "1", $fY);

    $prevMonth->setDate($y, $m - 1, "1", $fY);

    echo $thisMonth->fourYear; //echoes nothing

    $weekDay = $thisMonth->getMonthFirst();

    $testYear = $thisMonth->getYear();

    $i = $prevMonth->getMonthMax() - $weekDay;

    $totalDays = $weekDay + $thisMonth->getMonthMax();

    $totalWeeks = ceil($totalDays / 7);

    $days = $totalWeeks * 7;

    $prevMonthMax = $prevMonth->getMonthMax();

    $thisMonthMax = $thisMonth->getMonthMax();

    $nextMonthMax = $nextMonth->getMonthMax();

    ?>

正在定义对象，因为标志回波从它们内部输出到屏幕。我原本以为它可以使用我自己的get函数但是当它不起作用时我开始更多地了解它并学习了魔术函数__set，__get但是我还没有完成那些。我是否必须重做我的大部分代码以适应魔术功能？或者有更简单，更容易的方法吗？特别是使用我当前的代码而没有打算重复使用此代码，所以我想让它100％正确，所以我永远不必重做它。

由于安德鲁

Answer 1

您的问题是，您从未将值分配给该类的对象属性“fourYear”。你这样做

$fourYear = 'new value';

你必须这样做：

$this->fourYear = 'new value';

请不要使用魔术函数__get和__set。你在这里不需要它们。你需要它们，如果你想在存储它之前对它做一些事情。

这是你的更新和工人阶级：
