"Weeks"? Really?

 

Array (
Whatever variable you dumped is an array,

[2] => WP_User Object (
[3] => WP_User Object (
containing WP_User objects,

[data] => stdClass Object (
with "data" properties that are plain stdClass objects,

[ID] => 3
[user_email] => noreply1@test.com
that contain "ID" and "user_email" properties.

 

foreach ($variable as $user) {
	echo "ID: {$user->data->ID}, Email: {$user->data->user_email}";
}

Hello,

 

Thanks for the help. So it starts like this:

 

 <?php
$userlist = get_users_who_favorited_post($post_id = null, $site_id = null); <--- gives the array above

 

what should I type here?

print_r($userlist)
?>

 

 

And I want a formula to get only ID´s .....and another formula to obtain only emails...

 

Thanks

Hey Guys,

Can someone give a little help?

I found that it returns 2 arrays. For example Array ( [0] => 3 ) Array ( [0] => 1 ) ....thats why the substr() is not working. Because if I tried to get the first element it would give me "31". And the second element would be "empty".

<?php
$userlist = get_users_who_favorited_post($post_id = null, $site_id = null);
foreach ($userlist as $user) {
$int= "{$user->data->ID}";  // 31   (not a sequence like I thought)
$arr1 = str_split($int);  
print_r($arr1);    //Array ( [0] => 3 ) Array ( [0] => 1 )
}
?>


I want to obtain the first element "3" .....and the second element "1" ....separately ...... how can i do this?

Thanks,
