Getting specific value from multidimensional array in PHP

Question

I am having a multidimensional array like this:

Array
(
    [0] => stdClass Object
        (
            [id] => 12
            [userid] => 001


        )

    [1] => stdClass Object
        (
            [id] => 13                
            [userid] => 002

        )

)

I want to display the userid values from both like "001, 002" as a string with comma separated.

You'll have be more specific as to what you want to do with the specific value. As it stands your question would suit a foreach, echoing out the values. Or setting them to vars — James, Nov 06 '14 at 21:15
Well that said, we could do some magic with `json_encode()` en `json_decode()` :P — HamZa, Nov 06 '14 at 21:16
Basically, i want to output the userid values in a string with comma separated from this array — denis, Nov 06 '14 at 21:19

It is not a multidimensional array, it is an array that contains objects, meaning you access the property inside of the object with an -> , not with []'s --- so to turn this into a list of comma-separated values, do this:

foreach($yourArray as $object){

   $finalString[] = $object->id; 

    }

echo implode(", ", $finalString);

If we call your array $arr, then I would use array_map:

$userIds = array_map(function($obj) { return $obj->userid; }, $arr);

If you want to output csv, I would use fputcsv like this (for example):

$handle = fopen('php://output', 'rw');
fputcsv($handle, $userIds);
