Hey Experts!!

Very simple and straight forward question: In my WP site, I have gotten back an array and want to know how to echo out the values I need.

Let's say I want to echo out display_name from the following:

array(205) { [0]=> object(WP_User)#619 (7) { ["data"]=> object(stdClass)#393 (10) { ["ID"]=> string(4) "2138" ["user_login"]=> string(23) "blah@blah.com" ["user_pass"]=> string(34) "fdasfasfsfasfa" ["user_nicename"]=> string(22) "akillileawcapgroup-com" ["user_email"]=> string(23) "blah@blah.com" ["user_url"]=> string(13) "http://Alison" ["user_registered"]=> string(19) "2013-06-08 23:59:31" ["user_activation_key"]=> string(0) "" ["user_status"]=> string(1) "0" ["display_name"]=> string(6) "Alison" } ["ID"]=> int(2138) ["caps"]=>

Open in new window


How can I do that?

To expand on my comment, you use [ ] brackets to access an array element by its index. Like:

$yourarray[0] is actually the WP_User object:
[0]=> object(WP_User)#619

Open in new window


To access a property of an object, you use the -> arrow:
$object->property

Open in new window


So for example, you could change the object's display_name like this:
$object->display_name = "New Name";

Open in new window


or to display it:
echo $object->display_name;

Open in new window


My first example accesses the first array element, which is an object, and then accesses its display_name property.

Your array (whatever the variable name is) contains 205 elements:
array(205)

Open in new window


So I'm assuming it is probably 205 unique WP_User objects. You could loop through the array and echo out all names like this:
foreach($yourarray as $user)
{
  echo $user->display_name . "<br>\n";
}
