php print array contents

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-

Try: foreach($userFlags['follow'] as $item) { var_dump ($item); } — anubhava

var_dump is similar to print_r - so we just get: code object(stdClass)#116 (7) { ["flagging_id"]=> string(2) "19" ["fid"]=> string(1) "5" ["entity_type"]=> string(4) "user" ["entity_id"]=> string(1) "1" ["uid"]=> string(2) "59" ["sid"]=> string(1) "0" ["timestamp"]=> string(10) "1385845765" } object(stdClass)#117 (7) { ["flagging_id"]=> string(2) "27" ["fid"]=> string(1) "5" ["entity_type"]=> string(4) "user" ["entity_id"]=> string(2) "17" ["uid"]=> string(2) "59" ["sid"]=> string(1) "0" ["timestamp"]=> string(10) "1386167853" } code — daveferrara1

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; }

We throw an error of: Fatal error: Cannot use object of type stdClass as array

//@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. }
