Question

我正在尝试使用Google Contacts API来显示我的所有联系人。我遵循了一个教程，但遗憾的是本教程没有展示如何在我的网站上显示数据。如果重要的话，我也在使用Google App Engine和PHPStorm ......

    foreach ($google_contacts as $contacts){
        echo'<tr>';
        echo'<td>'. $contacts['title']."</td>";
        echo'<td>'. $contacts['gd$email'].'</td>';
        echo'</tr>';

当您遍历$ google_contacts数组时，您使用了错误的数组键。

更改此

foreach ($google_contacts as $contacts){
    echo'<tr>';
    echo'<td>'. $contacts['title']."</td>";
    echo'<td>'. $contacts['gd$email'].'</td>';
    echo'</tr>';
}

到此

foreach ($google_contacts as $contacts){
    echo'<tr>';
    echo'<td>'. $contacts['name']."</td>";
    echo'<td>'. $contacts['email'].'</td>';
    echo'</tr>';
}

如何将数组中的值放入HTML表？
