I have a line of code to get attributes :
$attributes = $as->getAttributes();
When i use print_r
$results = print_r($attributes);
This is what i get :
Array
(
[http://schemas.microsoft.com/2012/12/certificatecontext/extension/subjectkeyidentifier] => Array
(
[0] => username
)
[http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress] => Array
(
[0] => email#mail.com
)
[http://schemas.xmlsoap.org/claims/CommonName] => Array
(
[0] => User lastname
)
[http://schemas.xmlsoap.org/ws/2005/05/identity/claims/upn] => Array
(
[0] => email#mail.com
)
[uid] => Array
(
[0] => user
)
)
How can i display those results with a foreach ?

Answer 1

To get all the informations you can use
foreach($attributes as $url=>$info)
{
echo $url; //example : http://schemas.microsoft.com/2012/12/certificatecontext/extension/subjectkeyidentifier
foreach($info as $key=>$attr)
{
echo $key; //example : 0
echo $attr; //example : username
}
}

Per your answers to the comments, you want to be able to format each row differently. Therefore, you could do something like the following:
<?php
foreach($attributes as $key => $value){
echo $key; // the key of the array
echo $value; // the value of the array row
echo '<br />'; // if you want a new line
}
However, if you want a common format, such as a list, you could use implode to do it for you (docs).
<?php
echo '<ul><li>'; // Open list and add first open tag
echo implode('</li><li>', $attributes);
echo '</li></ul>'; //Close last item and list element
And this would generate an HTML formatted list of the elements, though you certainly could do any delimiter that worked for your project.
