When I click on the <a> which stands in main.php to import the contacts and I click through the accepts of google so I allow them to see my contacts. And then when I return to own page... it doesn't show any contacts at all. I think it's because I don't return any contacts, but I don't know how.

You can use an var_dump() to see if the array google_contacts is actually filled. Put this in the main.php:
<?php
var_dump($google_contacts);
?>
If you get an output in the var_dump you can use an html table and an easy foreach, look below:
<table border='1' class="table table-striped table-condensed">
<thead>
<tr>
<th>Naam </th>
<th>Email </th>
</tr>
</thead>
<tbody>
<?php
foreach ($google_contacts as $contacts){
echo'<tr>';
echo'<td>'. $contacts['name']."</td>";
echo'<td>'. $contacts['email'].'</td>';
echo'</tr>';
}
?>
</tbody>
