display linkedin details in my text fields using php

[DamForums]

i have managed to connect with Linkedin APi, so i can get the users details using below code.

$response = $OBJ_linkedin->profile('~:(id,first-name,last-name,picture-url,email-address,phone-numbers)');

if($response['success'] === TRUE) {

$response['linkedin'] = new SimpleXMLElement($response['linkedin']); 

after that i need to display the retrieved details into text fields like this.

<table border="1">

<tr>

<td>Name</td>

<td><?php echo $response['linkedin']->id; ?></td>

</tr>



<tr>

<td>first Name</td>

<td><?php echo $response['linkedin']->first-name; ?></td>

</tr>



<tr>

<td>Email</td>

<td><?php echo $response['linkedin']->email-address; ?></td>

</tr>



</table> 

Id is displaying correctly, but other details are not showing. can anyone help on this. thanks in advance

Depending on what $response['linkedin'] looks like, maybe this:

$li = (array)$response['linkedin'];
//then
echo $li['first-name'];

But to use it as an object (PHP vars cannot contain hyphens):

echo $response['linkedin']->{'first-name'};
