Question

我的gmail帐户中有标签，例如嵌套标签（工作/编程）。我正在开发PHP，我有这个代码用于显示标签列表

$service_gmail = new Google_Service_Gmail( $client );
$lab = ( ! empty( $_GET['label'] ) ) ? $_GET['label'] : 'INBOX';
$labelsResponse = $service_gmail->users_labels->listUsersLabels('me');
$labels = array_merge($labels, $labelsResponse->getLabels());

<?php if ( ! empty( $labels ) ) { 
        foreach ( $labels as $key => $label ) :
        ?>
             <tr>
                <td width="1%"><span class="num"><?php echo ( $key + 1 ); ?></span></td>
                <td><h5><?php echo $label['name'];?></h5>
                    <small><?php echo $label['type'];?></small></td>
                <td><?php echo $service_gmail->users_labels->get( 'me', $label['id'] )->getMessagesUnread();?></td>
                <td><?php echo $service_gmail->users_labels->get( 'me', $label['id'] )->getMessagesTotal(); ?></td>
            </tr>
            <?php
        endforeach;
    }
?>

但我希望将嵌套标签显示为主标签的子标签，如此

   Work
     - accounting
     - programming
     - ......
  Social
     - facebook (Social/facebook)
     - twitter (Social/twitter)

因此可以在没有硬编码的情况下完成它，所以我需要一切都是动态的吗？

你将有2个数组$ main_labels和$ sub_labels。在foreach循环中，您将看到标签名称是否包含字符'/'。如果是，您将用'/'标记（）标签名称。然后，如果第一部分（在/之前）已存在，您将在$ main_labels中搜索。如果是，则将第二部分存储在$ sub_labels中。最后，为了回显标签，你将遍历$ main_labels数组，在循环内你将看到$ sub_labels [$ main_lbl_key]是否为空。如果它不是空的，则有子类别，你必须在$ sub_labels [$ main_lbl_key]上写另一个循环来回显它们。

例如：

<?php

$service_gmail = new Google_Service_Gmail( $client );
$lab = ( ! empty( $_GET['label'] ) ) ? $_GET['label'] : 'INBOX';
$labelsResponse = $service_gmail->users_labels->listUsersLabels('me');
$labels = array_merge($labels, $labelsResponse->getLabels());

$main_labels = $sub_labels = array();

function ifMainLabelExists($lbl) {
    global $main_labels;
    foreach ($main_labels as $k => $l) {
        if (strcmp($lbl['name'], $l) === 0) {
            return $k;
        }
    }

    return -1;
}

if ( ! empty( $labels ) ) { 
    foreach ( $labels as $key => $label ) {
        if (strpos($label['name'], '/') !== false) {
            $label_parts = explode('/', $label['name']); // break label name at  character '/'
            if (count($label_parts) > 1) {
                $m = ifMainLabelExists($label_parts[0]);
                if ($m !== -1) { // main label already exists
                    $label['name'] = $label_parts[1];
                    $sub_labels[$m][] = $label;
                } else { // main label does not exist already
                    $label['name'] = $label_parts[0];
                    $main_labels[] = $label;
                    $m = count($main_labels) - 1; // will be inserted at last index

                    $label['name'] = $label_parts[1];
                    $sub_labels[$m][] = $label;
                }
            }
        } else {
            $main_labels[] = $label;
        }
    }
}

// now echo them
