访问数组和对象 [英] accessing array and objects

问题描述

我有我的打印数据的问题。在我的计划，我得到这是在对象放在一个阵列中的数据。说数组1 [$ ID] =数据对象。整个数组1，然后将被投入到ARRAY2 ['名单']像数组2 ['名单'] = ARRAY1;

问题是如何获得的数据，如ID，名称和说明。这里是整个阵列的print_r：

这实际上是数组的结果，我不知道如何访问此。我想的foreach并获得名字，并打印出来：

 阵列（
[名单] =＆GT;阵列（
    [0] =＆GT;阵列（
        [0] =＆GT; stdClass的对象（
            [ID] =＆GT; 1
            [名] =＆GT;哈利·波特4
            [说明] =＆GT;哈利·波特与火的书由J.K.高脚杯罗琳
            [UNIT_PRICE] =＆GT; 300.99
        ）
    ）
    [1] =＆GT;阵列（
        [0] =＆GT; stdClass的对象（
            [ID] =＆GT; 4
            [名] =＆GT;立顿红茶
            [说明] =＆GT;黄色标签茶
            [UNIT_PRICE] =＆GT; 15.00
        ）
    ）
    [2] =＆GT;阵列（
        [0] =＆GT; stdClass的对象（
            [ID] =＆GT; 9
            [名] =＆GT; tisyu
            [说明] =＆GT;组织二十几块
            [UNIT_PRICE] =＆GT; 20.00
        ）
    ）））
 

解决方案

您将不得不访问它们类似如下：

 的foreach（$数组['名单']为$ array_item）{
    $对象= $ array_item [0];    回声$对象 - ＆GT; ID＆LT; BR /＆gt;中。
    回声对象 -  $＆GT;的名字。＆LT; BR /＆gt;中;
    回声$对象 - ＆GT;的说明。＆LT; BR /＆gt;中;
    回声$对象 - ＆GT; UNIT_PRICE。＆LT; BR /＆gt;中;
}
 

这将产生：

  1
哈利·波特4
哈利·波特与火的书由J.K.高脚杯罗琳
300.99
4
立顿红茶
黄色标签茶
15.00
9
tisyu
tussue二十几块
20.00
 

您可以通过访问一个对象的属性 - >运营商，其次是你要访问的属性。

I have a problem with printing my data. In my program, i get the data which was in object and put in an array. say array1[$id] = dataobject. the whole array1 then will be put to array2['list'] like array2['list'] = array1;

the problem is how do i get the data such as the id, name and description.. here's the print_r of the whole array:

this is actually the result of the array, i am not sure how to access this. i want to foreach and get the name and print them:

Array ( 
[list] => Array ( 
    [0] => Array ( 
        [0] => stdClass Object ( 
            [id] => 1 
            [name] => harry potter 4 
            [description] => harry potter and the goblet of fire book by j.k. rowling 
            [unit_price] => 300.99 
        ) 
    ) 
    [1] => Array (
        [0] => stdClass Object ( 
            [id] => 4
            [name] => lipton tea
            [description] => yellow label tea
            [unit_price] => 15.00 
        ) 
    ) 
    [2] => Array (
        [0] => stdClass Object (
            [id] => 9
            [name] => tisyu
            [description] => tissue twenty pieces
            [unit_price] => 20.00
        ) 
    )

) 

)

解决方案

You would have to access them something like the following:

foreach($array['list'] as $array_item){
    $object = $array_item[0];

    echo $object->id."<br />";
    echo $object->name."<br />";
    echo $object->description."<br />";
    echo $object->unit_price."<br />";
}

This would yield:

1
harry potter 4
harry potter and the goblet of fire book by j.k. rowling
300.99
4
lipton tea
yellow label tea
15.00
9
tisyu
tussue twenty pieces
20.00

You can access an objects properties using the -> operator, followed by the property you wish to access.
