php print array contents - php

Question

I need help printing the contents of this function:
which came from:
http://drupalcontrib.org/api/drupal/contributions%21flag%21flag.module/function/flag_get_user_flags/7
$userFlags = flag_get_user_flags('user', null, $node->uid, null, false);
If I use print_r:
print '<pre>';
print_r(flag_get_user_flags('user', null, $node->uid, null, false));
print '</pre>';
I get -
Array
(
[follow] => Array
(
[13] => stdClass Object
(
[flagging_id] => 20
[fid] => 5
[entity_type] => user
[entity_id] => 13
[uid] => 1
[sid] => 0
[timestamp] => 1385845849
)
[15] => stdClass Object
(
[flagging_id] => 21
[fid] => 5
[entity_type] => user
[entity_id] => 15
[uid] => 1
[sid] => 0
[timestamp] => 1385912237
)
[17] => stdClass Object
(
[flagging_id] => 22
[fid] => 5
[entity_type] => user
[entity_id] => 17
[uid] => 1
[sid] => 0
[timestamp] => 1386040495
)
[18] => stdClass Object
(
[flagging_id] => 23
[fid] => 5
[entity_type] => user
[entity_id] => 18
[uid] => 1
[sid] => 0
[timestamp] => 1386040515
)
[21] => stdClass Object
(
[flagging_id] => 24
[fid] => 5
[entity_type] => user
[entity_id] => 21
[uid] => 1
[sid] => 0
[timestamp] => 1386043939
)
[14] => stdClass Object
(
[flagging_id] => 25
[fid] => 5
[entity_type] => user
[entity_id] => 14
[uid] => 1
[sid] => 0
[timestamp] => 1386129658
)
)
)
When I use:
foreach($userFlags as $item) {
echo $item;
}
All i get is the word "Array" printed. If your familiar with drupal ideally I need to convert each entity_id to its author. printing the 13,15 etc. is a good start for me.
thanks for any help-

Answer 1

You have an array in an array. Pull the inner array out before your foreach:
$follow = $userFlags['follow'];
foreach($follow as $item) {
echo $item->entity_id;
}
Or more succinctly:
foreach($userFlags['follow'] as $item) {
echo $item->entity_id;
}

Answer 2

//#parram $data-array,$d-if true then die by default it is false
//#author Your name
function p($data,$d = false){
echo "<pre>";
print_r($data);
echo "</pre>";
if($d == TRUE){
die();
}
} // END OF FUNCTION
Use this function every time whenver you need to string or array it will wroks just GREAT. There are 2 Patameters 1.$data - It can be Array or String 2.$d - By Default it is FALSE but if you set to true then it will execute die() function
In your case you can write like this..
$userFlags = flag_get_user_flags('user', null, $node->uid, null, false);
foreach($userFlags as $item) {
p($item['id']); // If it is array
p($item->id); // If it is an Object
// To get benefit of this code Use above function of p in your code.
}
