尝试这样：

  print< h2>您遵循的群组：< / h2> \\\
< ul>; 
 foreach（$ groups ['data'] as $ group）{
 $ group_name = $ group ['name']; 
 $ group_id = $ group ['id']; 
 printf（< li>％s  -  ID =％s< / li> \\\
，$ group_name，$ group_id）; 
} 
 print< / ul>; 
 

Could someone point me in the right direction to how I can get a list of all the groups a specific user is connected to using the facebook graph api?

I have this:

$groups = $facebook->api( '/me/groups', 'GET', array( 'access_token=' => $membertoken ) );

If I use print_r($groups) I can see the array is returning all the groups, but how can I seperate the array to list just the group names and group ID into seperate strings so I can use them in a database etc?

Try this:

print "<h2>Here are the groups you follow:</h2>\n<ul>";
foreach ($groups['data'] as $group) {
    $group_name = $group['name'];
    $group_id = $group['id'];
    printf("<li>%s - ID = %s</li>\n", $group_name, $group_id);
}
print "</ul>";
