I use the following code to generate a encrypted string for a given string.

class MY_class{
    public static function cryption($string){
        $output = base64_encode(openssl_encrypt($string, $cipher_method, $key, 0, $iv));
        $output = $iv . $output;
        return $output;

Using this code I generated the encrypted id of the id of a model object and replaced the original id.

$Model_object = Model_class::find(1);
$Model_object->id = MY_class::cryption($Model_object->id);
echo json_encode($Model_object);

For a given instance print_r() of $Model_object after replacing the original id with encrypted id gives me the following result.

[index] => Array
        [id] => 4df73f34cUYxVmVLWlFUU2M9

But json_encode() only outputs only the first decimal digits of the of the encrypted id.


I'd really appreciate if someone can explain why this is happening and how to overcome this problem.

P.S. I have already googled this problem and searched in Stack Overflow too. So, don't mention it in comments.

    As @LSerni said, I was implicitly assigning the encrypted id which is a string to the integer property $Model_object->id.

    So I created a new dynamic property $Model_object->encrypted_id and assigned the encrypted id to it and called that property on the other side. It worked like a charm.

    Thank you very much @LSerni for your insight on the problem.
