Php 多维数组-foreach，在foreach中

我有一个多维数组，它正以我想要的方式打印出来，然而，我一直在思考如何将它构建到我正在寻找的for-each循环中

请注意：$handle是客户端在后端输入的字段

<?php
$gp = Mage::getStoreConfig('social_code/social_group/google_field');
$ld = Mage::getStoreConfig('social_code/social_group/linkedin_field');
$tw = Mage::getStoreConfig('social_code/social_group/twitter_field');
$fb = Mage::getStoreConfig('social_code/social_group/facebook_field');

$social_array = array(
    "facebook" => array(
        'class' => "facebook",
        'url' => 'https://www.facebook.com/',
        'handle' => $fb
    ),
    "twitter" => array(
        'class' => "twitter",
        'url' => 'https://www.twitter.com/',
        'handle' => $tw
    ),
    "linked-in" => array(
        'class' => "linked-in",
        'url' => 'http://www.linkedin.com/company/',
        'handle' => $ld
    ),
    "google-plus" => array(
        'class' => "google-plus",
        'url' => 'https://plus.google.com/',
        'handle' => $gp
    )
);
?>

现在我想把它作为一个无序的列表，所以我有下面的，但它仍然不适合我

<ul>
        <?php foreach ($social_array as $name => $group) :?>
            <?php foreach ($group as $class => $url) :?>
                <li><a href="<?php echo ("$url"); ?>" class="<?php echo ("$class;") ?>"><?php echo ("$group"); ?></a></li>
            <?php endforeach; ?>
        <?php endforeach; ?>
    </ul>

我希望它能在所有的社交圈中循环，并引发类似的结果

<li><a href="<?php echo ($url);?><?php echo ($handle);?>" class="<?php echo ($class); ?>"><?php echo $name; ?></a></li>

或者更容易理解

<li><a href="http://www.facebook.com/handle" class="facebook">Facebook</a></li>

另外，如果我把这件事弄得过于复杂，请让我知道。

试一试：

<ul>
    <?php foreach ($social_array as $name => $properties) :?>
        <li><a href="<?php echo ($properties["url"] . $properties["handle"]); ?>" class="<?php echo ($properties["class"]); ?>"><?php echo ucfirst($name); ?></a></li>
    <?php endforeach; ?>
</ul>

在这个foreach中，语法是

foreach（$key=>$value数组）

，因此这里

$name

是$social\u数组中的键，

$properties

是与该键关联的数组。

试一试：

<ul>
    <?php foreach ($social_array as $name => $properties) :?>
        <li><a href="<?php echo ($properties["url"] . $properties["handle"]); ?>" class="<?php echo ($properties["class"]); ?>"><?php echo ucfirst($name); ?></a></li>
    <?php endforeach; ?>
</ul>

<ul>
    <?php foreach ($social_array as $name => $group) :?>
        <li><a href="<?php echo $group['url'].$group['handle']; ?>" class="<?php echo $group['class']; ?>"><?php echo $name; ?></a></li>
    <?php endforeach; ?>
</ul>

，因此这里

$name

$properties

<ul>

        <li><a href="<?php echo $group['url'].$group['handle']; ?>" class="<?php echo $group['class']; ?>"><?php echo $name; ?></a></li>
    <?php endforeach; ?>
</ul>

如果我理解正确，我想这就是你要找的

<ul>
        <?php foreach ($social_array as $name => $group) :?>
                <li><a href="<?php echo $group['url'].$group[handle']; ?>" class="<?php echo $group['class']; ?>"><?php echo $name
        <?php endforeach; ?>
</ul>

如果我理解正确的话，我想这就是你要找的

<ul>
        <?php foreach ($social_array as $name => $group) :?>
                <li><a href="<?php echo $group['url'].$group[handle']; ?>" class="<?php echo $group['class']; ?>"><?php echo $name
        <?php endforeach; ?>
</ul>


没有必要对内部进行检查

<?php foreach ($social_array as $name => $group) :?>
        <li><a href="<?php echo $group['url'] ?>" class="<?php echo $group['class'] ?>"><?php echo $group['class']; ?></a></li>
<?php endforeach; ?>



无需使用内部foreach

<?php foreach ($social_array as $name => $group) :?>
        <li><a href="<?php echo $group['url'] ?>" class="<?php echo $group['class'] ?>"><?php echo $group['class']; ?></a></li>
<?php endforeach; ?>

您忘记的是，内部的
foreach
正在处理每个项目，即
类、ulr、句柄
一次处理一个项目

因此，您需要在传递3个项目时存储所需的信息，以便在获得实际需要的2个项目后可以使用这些信息

所以这可能会有所帮助

<ul>
<?php 
    foreach ($social_array as $name => $group) :

        $class    = NULL;
        $url      = NULL;
        $handle   = NULL;

        foreach ($group as $name => $value) :

            switch ($name) :
               case 'class'   : $class  = $value;     break;
               case 'url'     : $url    = $value;     break;
               case 'handle'  : $handle = $value;     break;
            endswitch;

            if ( isset($class) AND isset($url) AND isset($handle) ) :

               echo '<li><a href="' . $url.$handle . '" class="' . $class . '">' . $group . '</a></li>';

               $class   = NULL;
               $url     = NULL;
               $handle  = NULL;
            endif;

        endforeach;

    endforeach;
?>
</ul>

这看起来很有用，我会试试看。谢谢。这个看起来很有用，我会试试的。谢谢
