Multidimensional array to string php

I have below array and i am trying to convert to string separated with comma.

$users_array = Array
(
[0] => Array
    (
        [0] => Array
            (
                [user_id] => 1
            )

        [1] => Array
            (
                [user_id] => 5
            )

    )

[1] => Array
    (
        [0] => Array
            (
                [user_id] => 6
            )

        [1] => Array
            (
                [user_id] => 13
            )

    )

)

Then i tried to convert in string with foreach

for($i = 0; $i < count($users_array); $i++){
    $xyz[] = implode(",",$users_array[$i]);
}
$users = implode(',',$xyz);

But it throw error Message: Array to string conversion

How can i convert it to string like 1,5,6,13?

Thank you,

hey @rjcode in php if you want to convert an array to comma separated string so use function implode(separation letter, $array) and for vice versa means string to an array so use function explode(separation letter, string)

for your case use use implode() so for your code try below one

 <?php
    for($i = 0; $i < count($users_array); $i++){
   for($j = 0; $j < count($users_array[$i]; $j++)) {
       $xyz[] = $users_array[$i][$j]["user_id"];
    }
    }
    $users = implode(',',$xyz);
?>

$user_ids = array();
foreach($users_array as $val){
    foreach($val as $v)){
       array_push($user_ids,$v['user_id']);
    }
} 
$users = implode(',',$user_ids);

This code is very easy and also use for as per your requirement.
