How to decode a JSON string in PHP?

Question

I have a JSON string that looks something like this:

{\"addresses\":{\"address\":[{\"@array\":\"true\",\"@id\":\"888888\",\"@uri\":\"xyz\",\"household\":{\"@         


        

Answer 1

This one will put all scalar and null values into session where key does not begin with a @

$jsonString = '{"addresses":{"address":[{"@array":"true","@id":"888888","@uri":"xyz","household":{"@id":"44444","@uri":"xyz"},"person":{"@id":"","@uri":""},"addressType":{"@id":"1","@uri":"xyz","name":"Primary"},"address1":"xyz","address2":null,"address3":null,"city":"xyz","postalCode":"111111"}]}}';

$result = json_decode($jsonString);

// will put *all* scalar and null values into session where key does not begin with a @
foreach($result->addresses->address[0] as $key=>$value) {
    if (substr($key, 0, 1) != '@'  && (is_scalar($value) || is_null($value)) ) {
        $_SESSION[$key] = $value;
    } 
}

print_r($_SESSION);
