PHP的多维度阵列？ [英] php multi dimension array?

问题描述

我检索来自API，多维数组PHP（我认为）现在所有的值返回完美，当我转储阵列的print_r我得到这样的：

I am retrieving a multidimensional php array (I think) from an API, now all of the values return perfectly and when I dump the array with print_r I get this:

 Event Object
(
    [title] => test
    [link] => google.com
    [updated] => 2013-03-06T12:08:56.521-05:00
    [id] => test
    [name] => Copy of Copy of Copy of Mar 05, 2013 - TEST4
    [description] => 
    [registered] => 2
    [createdDate] => 2013-03-06T12:08:56.521-05:00
    [status] => COMPLETE
    [eventType] => OTHER
    [eventLocation] => EventLocation Object
        (
            [location] => test
            [addr1] => test
            [addr2] => 
            [addr3] => 
            [city] => madrid
            [state] => andalucia
            [country] => 
            [postalCode] => 06103
        )

    [registrationUrl] => https://google.com
    [startDate] => 2013-03-07T13:00:00-05:00
    [endDate] => 2013-03-07T13:00:00-05:00
    [publishDate] => 2013-03-06T12:11:15.958-05:00
    [attendedCount] => 0
    [cancelledCount] => 0
    [eventFeeRequired] => FALSE
    [currencyType] => USD
    [paymentOptions] => Array
        (
        )

    [registrationTypes] => Array
        (
            [0] => RegistrationType Object
                (
                    [name] => 
                    [registrationLimit] => 
                    [registrationClosedManually] => 
                    [guestLimit] => 
                    [ticketing] => 
                    [eventFees] => Array
                        (
                        )

                )

        )

)

现在通过机智装模作样的我基本的PHP我发现，我可以列出所有的第一阵列项目从[标题]到[EVENTTYPE]是这样的：

Now bumbling through wit my basic PHP i have found that i can list all of the first array items from [title] to [eventType] like this:

<?php 
    // get details for the first event returned
    $Event = $ConstantContact->getEventDetails($events['events'][0]);
     reset($Event);
    while (list($key, $value) = each($Event)) {
        echo "$key => $value \r\n<br/>";
    }
    ?>

我的问题：所有我需要做的是检索[标题]和[的startDate]我不需要休息，现在我可以用js和css只是躲在休息，但我相信我只是作为一个白痴，有是遍历数组所以它只吐出来的是两个值我需要一个更简单的方法。
我该怎么做呢？

my question: All I need to do it retrieve [title] and [startDate] I don't need the rest now I could just hide the rest using Js and css but i am sure i am just being an idiot and there is an easier way to traverse this array so it only spits out the two values i need. How do i do this?

推荐答案

您不必遍历整个对象。只需输入您想要的属性：

You do not have to traverse the whole object. Just access the properties you want:

$title = $Event->title;
$startDate = $Event->startDate;

// or
echo $Event->title;
echo $Event->startDate;

它实际上是一个对象 - 不可以的（关联）数组！


有什么区别？

It's actually an object - not an (associative) array!
What's the difference?

• 对象是类的一个实例。一个类的方法和属性（成员变量）。
  
  
  与C ++或其他一些OOP语言，可以动态地定义属性，无需在类声明，宣布他们。

• An object is an instance of a class. A class has methods and attributes (member variables).
  Unlike C++ or some other OOP languages, you can define attributes dynamically without declaring them in the class declaration.

数组是简单的按键和值的容器。

An array is simply a container for keys and their values.
