Question

我有以下数据：

Item 1
Title: Lorem ipsum dolor sit amet
Language: Deutsch

Item 2
Title: Lorem ipsum dolor sit amet
Language: Deutsch

Item 3
Title: Lorem ipsum dolor sit amet
Language: Englisch

Item 4
Title: Lorem ipsum dolor sit amet
Language: Franzoesisch

我希望只有“Deutsch”项目显示在案例中（“dev.domain.de”），“Englisch”项目显示在案例中（“dev.domain.com”）等等

 <?php 
      $strRendersettings = ($this->settings)? 'settings' : 'view';
 ?>
 <?php
      if (count($this->data)):
 ?>
    <ul>
      <?php
        switch($_SERVER['HTTP_HOST'])
        {
            case ("dev.domain.de"):
                if ($arrItem['text']['new_docs_auswahl'] == "Deutsch"){
                    foreach ($this->data as $arrItem): ?>
                        <li class="new_doc_home"><a href="" ><strong><?php echo $arrItem['text']['new_docs_titel']; ?>:</strong><br>
                                <p><?php echo $arrItem['text']['new_docs_Text']; ?></p></a>
                            <?php echo $arrItem['text']['new_docs_auswahl']; ?>
                        </li>
                    <?php
                    endforeach;
                }
                break;

            case ("dev.domain.com"):
                foreach ($this->data as $arrItem): ?>
                    <li class="new_doc_home"><a href="" ><strong><?php echo $arrItem['text']['new_docs_titel']; ?>:</strong><br>
                            <p><?php echo $arrItem['text']['new_docs_Text']; ?></p></a>
                        <?php echo $arrItem['text']['new_docs_auswahl']; ?>
                    </li>
                <?php
                endforeach;
                break;

            case ("dev.domain.fr"):
                foreach ($this->data as $arrItem): ?>
                    <li class="new_doc_home"><a href="" ><strong><?php echo $arrItem['text']['new_docs_titel']; ?>:</strong><br>
                            <p><?php echo $arrItem['text']['new_docs_Text']; ?></p></a>
                        <?php echo $arrItem['text']['new_docs_auswahl']; ?>
                    </li>
                <?php
                endforeach;
                break;
        }
        ?>
    </ul>

<?php else: ?>

<?php endif; ?>

Answer 1

这个伪代码可以是：

switch(host)
{
   case "de":
       select german data;
       break;
   case "fr":
       select french data;
       break;
   case "en":
   default:
       select english data;
       break;
 }

 foreach data as item
       display list element with item
 end

第一种情况下如果和 foreach 的顺序是错误的。请参阅固定和优化的变体：

<?php $strRendersettings = ($this->settings)? 'settings' : 'view'; ?>
<?php if (count($this->data)): ?>
    <ul>
        <?php
        $match = "";
        switch($_SERVER['HTTP_HOST'])
        {
            case "dev.domain.de":
                $match = "Deutsch";
                break;

            case "dev.domain.com":
                $match = "Englisch";
                break;

            case "dev.domain.fr":
                $match = "Franzoesisch";
                break;

        }

        foreach ($this->data as $arrItem) {
            if ($arrItem['text']['new_docs_auswahl'] == $match){
                ?>
                <li class="new_doc_home"><a href="" ><strong><?=$arrItem['text']['new_docs_titel']?>:</strong><br></a>
                        <p><a href="" ><?=$arrItem['text']['new_docs_Text']?></a></p>
                    <?=$arrItem['text']['new_docs_auswahl']?>
                </li>
                <?
            }
        }
        ?>
    </ul>
<?php endif; ?>

并且请检查W3C有关标记嵌套顺序的信息。

如果声明php不起作用
