Question

我有以下代码

公共函数returnArrayOfXmlElements（字符串$ xml_path，字符串$ element_key） {

        // Variables
        $this->simplexml_array    = (array)$this->returnSimpleXmlObject($xml_path);

        // Variables With Dependencies
        $this->xml_elements       = $this->simplexml_array[$element_key];

        foreach ($this->xml_elements as $this->array_key => $this->array_value) {

            $this->xml_elements_rectified[] = (array)$this->array_value;

        }

        return $this->xml_elements_rectified;

    }

当我尝试这个时，

switch ($menu_name) {

            case 'secondary':

                    // Variables
                    $this->menu_directory    = constant('ENVIRONMENT_DIRECTORY_FRONTEND_MENU_SECONDARY');
                    $this->request_uri       = (empty($_GET['request']) !== TRUE ? $_GET['request'] : constant('SETTING_TEMPLATE_DEFAULT'));

                    // Variables With Dependencies
                    $this->section_name      = strtolower(substr($this->request_uri, 0, strpos($this->request_uri, '/')));
                    $this->menu_file         = $this->section_name.'.xml';
                    $this->menu_data         = $this->library_xml->returnArrayOfXmlElements($this->menu_directory.$this->menu_file, 'item');

                    echo '
                        <ul menu-secondary>
                            <li class="icon"><icon id="section-'.$this->section_name.'"></icon></li>
                    ';

                        foreach ($this->menu_data as $this->array_key => $this->menu_information) {

                            // Variables
                            $this->item_hook    = $this->menu_information['hook'];
                            $this->item_name    = $this->menu_information['name'];

                            echo '<li><a href="'.$this->item_hook.'">'.$this->item_name.'</a></li>';

                        }

                    echo '
                        </ul>
                    ';

                break;

            default:

                    // Variables
                    $this->menu_directory      = constant('ENVIRONMENT_DIRECTORY_FRONTEND_MENU');
                    $this->menu_file           = 'main.xml';

                    // Variables With Dependencies
                    $this->menu_data           = $this->library_xml->returnArrayOfXmlElements($this->menu_directory.$this->menu_file, 'item');

                    echo '
                        <ul menu-main>
                            <li>polybotes</li>
                    ';

                        foreach ($this->menu_data as $this->array_key => $this->menu_information) {

                            // Variables
                            $this->item_hook    = $this->menu_information['hook'];
                            $this->item_name    = $this->menu_information['name'];

                            echo '<li><a href="'.$this->item_hook.'">'.$this->item_name.'</a></li>';

                        }

                    echo '
                        </ul>
                    ';

                break;
        }

    }

辅助开关中的

$ this-> menu_data包含$ xml1和$ xml2的数据。如何防止这种情况？取消设置$ xml1不能解决问题。

XML文件如下所示：

$ xml1：

<?xml version="1.0" encoding="ISO-8859-1" ?>
<menu>

    <item>

        <name>Dashboard</name>
        <hook>/dashboard/view</hook>

    </item>

    <item>

        <name>Location</name>
        <hook>/location/list</hook>

    </item>

    <item>

        <name>Networks</name>
        <hook>/network/list</hook>

    </item>

    <item>

        <name>Devices</name>
        <hook>/device/list</hook>

    </item>

    <item>

        <name>Alarms &amp; Events</name>
        <hook>/alarm/list</hook>

    </item>

</menu>

$ xml2：

<?xml version="1.0" encoding="ISO-8859-1" ?>
<menu>

    <item>

        <name>Network List</name>
        <hook>/network/list</hook>

    </item>

    <item>

        <name>Add Network</name>
        <hook>/network/add</hook>

    </item>

</menu>

您能帮我还是指出正确的方向？预先感谢。

在方法returnArrayOfXmlElements中，您似乎总是使用$this->variableName，这会引起问题，因为它将在方法调用之间保留数据。

除非您确实需要保留此数据，否则请尝试从每个变量中删除$this-> ...

public function returnArrayOfXmlElements(string $xml_path, string $element_key) {

        // Variables
        $simplexml_array    = (array)$this->returnSimpleXmlObject($xml_path);

        // Variables With Dependencies
        $xml_elements       = $this->simplexml_array[$element_key];

        $xml_elements_rectified = [];

        foreach ($xml_elements as $this->array_key => $this->array_value) {

            $xml_elements_rectified[] = (array)$this->array_value;

        }

        return $xml_elements_rectified;

    }

SimpleXML返回组合的XML内容
