Question

我真的希望有人可以在这里帮助我，自从这个问题的最后几天以来我一直困扰着。我有以下xml对象数组：

Array
(
[0] => Car Object
    (
        [type:Car:private] => SimpleXMLElement Object
            (
                [0] => SUVS
            )

        [name:Car:private] => SimpleXMLElement Object
            (
                [0] => Generic Car 1
            )

        [origin:Car:private] => SimpleXMLElement Object
            (
                [0] => USA
            )

        [description:Car:private] => SimpleXMLElement Object
            (
                [0] => Random
            )

        [price:Car:private] => SimpleXMLElement Object
            (
                [0] => 22 000
            )

    )

[1] => Car Object
    (
        [type:Car:private] => SimpleXMLElement Object
            (
                [0] => SUVS
            )

        [name:Car:private] => SimpleXMLElement Object
            (
                [0] => Generic Car 2
            )

        [origin:Car:private] => SimpleXMLElement Object
            (
                [0] => USA
            )

        [description:Car:private] => SimpleXMLElement Object
            (
                [0] => Random
            )

        [price:Car:private] => SimpleXMLElement Object
            (
                [0] => 28 000
            )

    )

[2] => Car Object
    (
        [type:Car:private] => SimpleXMLElement Object
            (
                [0] => SUVS
            )

        [name:Car:private] => SimpleXMLElement Object
            (
                [0] => Generic Car 3
            )

        [origin:Car:private] => SimpleXMLElement Object
            (
                [0] => USA
            )

        [description:Car:private] => SimpleXMLElement Object
            (
                [0] => Random
            )

        [price:Car:private] => SimpleXMLElement Object
            (
                [0] => 29 000
            )

    )

[3] => Car Object
    (
        [type:Car:private] => SimpleXMLElement Object
            (
                [0] => Pickup
            )

        [name:Car:private] => SimpleXMLElement Object
            (
                [0] => Generic Truck 1
            )

        [origin:Car:private] => SimpleXMLElement Object
            (
                [0] => USA
            )

        [description:Car:private] => SimpleXMLElement Object
            (
                [0] => Random
            )

        [price:Car:private] => SimpleXMLElement Object
            (
                [0] => 31 000
            )

    )

    [4] => Car Object

        [price:Car:private] => SimpleXMLElement Object
            (
                [0] => 39 000
            )

    )

我有一个带有一些值的xml文件，我用简单的xml读取，然后用Car类创建了car对象。我试图解决这个问题几天了，如何显示这个数组中的数据，标题只出现一次像一个部分。见下面的例子。

SUVS

通用汽车1 美国随机 22 000

通用汽车2 美国随机 28 000

通用汽车3 美国随机 29 000

拾取

通用卡车1 美国随机 31 000

通用卡车2 美国随机 39 000

您的部分似乎基于XML中类型值的内容。

我有2个想法来解决这个问题。

第一个想法： 如果您有一个foreach循环来创建您的部分，您可以在打印汽车名称之前查看类型：

//example code

echo '<strong>SUVS</strong>';
foreach($cars as $car){
    if($car->getType() == 'SUVS'){
        //create your output for a Car object
    }
}

echo '<strong>Pickups</strong>';
foreach($cars as $car){
    if($car->getType() == 'Pickup'){
        //create your output for a Car object
    }
}

第二个想法：修改您的阅读程序。

目前，您正在使用Car对象创建一个数组。创建Car对象时，应该已知车型。因此，您可以将不同类型的Car对象添加到不同的数组中。

这里有一些示例代码：而不是像这样创建一个数组

$array[] = new Car()

你可以创建像这样的东西

$car = new Car();
$type = $car->getType(); // returns 'Pickup' or 'SUVS'
//perhaps it is necessary to convert SimpleXMLElement objects to a string:
// $string = (string)$simplexmlelement;
$array[$type][] = $car;

然后你可以创建一个foreach循环来创建两个列表：

foreach($cars as $type => $carArray){
    echo '<strong>'.$type.'</strong>';
    foreach($carArray as $car){
        //create your output for a Car object
    }
}

或分别在每个列表上：

echo '<strong>Pickups</strong>';
foreach($cars['Pickup'] as $car){
    //create your output for a Car object
}

//Some other code

echo '<strong>SUVS</strong>';
foreach($cars['SUVS'] as $car){
    //create your output for a Car object
}.

代码片段只是用来说明这些想法的例子。
