array to string conversion return error of stdClass

Question

    if($stmt->execute()){
        $user = $stmt->get_result();
        while ($obj = $user->fetch_object()) {
             $result[] = $obj;
        }
    }

$result1encoded = json_encode($result);
echo $result1encoded;
// [{"uId":"1","firstName":"John"}]

I used implode like this :

    echo $result1encoded = implode(' ',$result1);
// expecting '[{"uId":"1","firstName":"John"}]'

But it says

Object of class stdClass could not be converted to string

$result1 is array of object. So, as array elements are objects here, they cannot be converted to string. implode expects string elements. — Kasun Rajapaksha, Apr 25 '14 at 05:02
why you wan to use `implode` when you are already getting result using `json_encode` — SajithNair, Apr 25 '14 at 05:05

To convert Array to String you can use serialize() method like this

$result1encoded = json_encode($result);

echo serialize($result1encoded);

Another Way to do is

 $result1encoded = json_encode($result);

echo $result1 = implode(' ',$result1encoded);

You can use array_map("json_encode", $your_array) to first convert each element of the array to string, and then use implode to glue it together.

See this https://eval.in/141541

<?php

$a = array();

$a[0]  = new stdClass();
$a[0]->uId = "1";
$a[0]->firstName = "John";

$a[1]  = new stdClass();
$a[1]->uId = "2";
$a[1]->firstName = "Albert";

$b = array_map("json_encode", $a);
echo implode(' ', $b);

?>
