当我单击main中的<a>.php导入联系人时，我单击Google的接受，以便他们看到我的联系人。然后当我回到自己的页面时...它根本不显示任何联系人。我想这是因为我没有返回任何联系人，但我不知道如何返回。

代码执行的最后一件事是设置"$google_contacts = $return"，因此由您的应用对 $google_contacts 数组执行一些有用的操作，例如显示它。此代码源自的博客未提及代码示例显示任何内容，只是提及它是如何检索联系人的示例。
您可以使用
var_dump（） 来查看数组google_contacts是否实际填充。 把这个放在主要.php：
<?php
var_dump($google_contacts);
?>
如果你在var_dump中获得输出，你可以使用一个html表格和一个简单的foreach，看看下面：
<table border='1' class="table table-striped table-condensed">
<thead>
<tr>
<th>Naam </th>
<th>Email </th>
</tr>
</thead>
<tbody>
<?php
foreach ($google_contacts as $contacts){
echo'<tr>';
echo'<td>'. $contacts['name']."</td>";
echo'<td>'. $contacts['email'].'</td>';
echo'</tr>';
}
?>
</tbody>
