json_decode не работает на строковой переменной

Question

Я пытаюсь декодировать строку json в php-массив, и я получаю синтаксическую ошибку (4), когда я использую json_last_error().

Строка поступает из вызова API в базу данных Infusionsoft. База данных возвращает массив с одной парой ключ/значение. Значение содержит строку json.

Array ([_PMSChargeItems] => [{"Date":"2012-09-07T00:00:00","Amount":0.0},{"Date":"2012-09-07T00:00:00","Amount":41.0},{"Date":"2012-09-07T00:00:00","Amount":64.0},{"Date":"2012-09-11T00:00:00","Amount":80.0},{"Date":"2012-09-11T00:00:00","Amount":474.0},{"Date":"2012-09-19T00:00:00","Amount":82.0},{"Date":"2012-09-19T00:00:00","Amount":125.0},{"Date":"2012-09-19T00:00:00","Amount":127.0},{"Date":"2012-09-19T00:00:00","Amount":174.0},{"Date":"2012-09-19T00:00:00","Amount":343.0},{"Date":"2012-09-19T00:00:00","Amount":618.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-27T00:00:00","Amount":0.0},{"Date":"2012-10-02T00:00:00","Amount":0.0},{"Date":"2012-10-02T00:00:00","Amount":0.0},{"Date":"2012-10-10T00:00:00","Amount":0.0},{"Date":"2012-11-07T00:00:00","Amount":0.0},{"Date":"2012-11-19T00:00:00","Amount":64.0},{"Date":"2012-12-21T00:00:00","Amount":0.0},{"Date":"2013-02-01T00:00:00","Amount":0.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":625.0},{"Date":"2013-02-01T00:00:00","Amount":625.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-13T00:00:00","Amount":0.0},{"Date":"2013-02-18T00:00:00","Amount":0.0},{"Date":"2013-02-25T00:00:00","Amount":65.0},{"Date":"2013-02-25T00:00:00","Amount":85.0},{"Date":"2013-03-11T00:00:00","Amount":0.0},{"Date":"2013-03-14T00:00:00","Amount":0.0},{"Date":"2013-03-14T00:00:00","Amount":0.0},{"Date":"2013-03-20T00:00:00","Amount":240.0},{"Date":"2013-06-12T00:00:00","Amount":0.0},{"Date":"2013-07-23T00:00:00","Amount":0.0},{"Date":"2013-07-26T00:00:00","Amount":0.0},{"Date":"2013-08-23T00:00:00","Amount":0.0},{"Date":"2013-09-09T00:00:00","Amount":0.0},{"Date":"2014-08-04T00:00:00","Amount":0.0},{"Date":"2014-08-11T00:00:00","Amount":30.0},{"Date":"2014-08-11T00:00:00","Amount":66.0},{"Date":"2014-08-11T00:00:00","Amount":85.0},{"Date":"2014-09-02T00:00:00","Amount":0.0},{"Date":"2014-12-16T00:00:00","Amount":0.0},{"Date":"2015-01-09T00:00:00","Amount":0.0},{"Date":"2015-02-10T00:00:00","Amount":14.0},{"Date":"2015-02-10T00:00:00","Amount":16.0},{"Date":"2015-02-10T00:00:00","Amount":43.0},{"Date":"2015-02-10T00:00:00","Amount":130.0},{"Date":"2015-02-10T00:00:00","Amount":130.0},{"Date":"2015-02-10T00:00:00","Amount":250.0},{"Date":"2015-02-10T00:00:00","Amount":640.0},{"Date":"2015-02-23T00:00:00","Amount":0.0},{"Date":"2015-02-25T00:00:00","Amount":0.0},{"Date":"2015-02-25T00:00:00","Amount":0.0},{"Date":"2015-03-26T00:00:00","Amount":0.0},{"Date":"2015-05-21T00:00:00","Amount":0.0}]) 

Когда я сохранить значение переменной строки и передать его json_decode() я получаю ошибку синтаксиса (она не работает). Если я передаю всю строку json (копировать и вставлять из эха значения строки var) в json_decode(), массив создается (он работает).

Я проверил строку json как на http://jsonlint.com/, так и на http://www.functions-online.com/json_decode.html.

Как я могу заставить строку правильно декодироваться, когда она передается функции json_decode с использованием переменной?

Вот код, я использую для декодирования:

$cid = $_GET['Id']; 
$returnFields = array('_PMSChargeItems'); 
$conDat = $appConnect->dsLoad("Contact", $cid, $returnFields); 

$a = $conDat['_PMSChargeItems']; 
var_dump(json_decode($a, true)); 

echo json_last_error(); 

Вот результат var_dump ($ а) перед декодированием:

string(4649) "[{"Date":"2012-09-07T00:00:00","Amount":0.0},{"Date":"2012-09-07T00:00:00","Amount":41.0},{"Date":"2012-09-07T00:00:00","Amount":64.0},{"Date":"2012-09-11T00:00:00","Amount":80.0},{"Date":"2012-09-11T00:00:00","Amount":474.0},{"Date":"2012-09-19T00:00:00","Amount":82.0},{"Date":"2012-09-19T00:00:00","Amount":125.0},{"Date":"2012-09-19T00:00:00","Amount":127.0},{"Date":"2012-09-19T00:00:00","Amount":174.0},{"Date":"2012-09-19T00:00:00","Amount":343.0},{"Date":"2012-09-19T00:00:00","Amount":618.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-27T00:00:00","Amount":0.0},{"Date":"2012-10-02T00:00:00","Amount":0.0},{"Date":"2012-10-02T00:00:00","Amount":0.0},{"Date":"2012-10-10T00:00:00","Amount":0.0},{"Date":"2012-11-07T00:00:00","Amount":0.0},{"Date":"2012-11-19T00:00:00","Amount":64.0},{"Date":"2012-12-21T00:00:00","Amount":0.0},{"Date":"2013-02-01T00:00:00","Amount":0.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":625.0},{"Date":"2013-02-01T00:00:00","Amount":625.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-13T00:00:00","Amount":0.0},{"Date":"2013-02-18T00:00:00","Amount":0.0},{"Date":"2013-02-25T00:00:00","Amount":65.0},{"Date":"2013-02-25T00:00:00","Amount":85.0},{"Date":"2013-03-11T00:00:00","Amount":0.0},{"Date":"2013-03-14T00:00:00","Amount":0.0},{"Date":"2013-03-14T00:00:00","Amount":0.0},{"Date":"2013-03-20T00:00:00","Amount":240.0},{"Date":"2013-06-12T00:00:00","Amount":0.0},{"Date":"2013-07-23T00:00:00","Amount":0.0},{"Date":"2013-07-26T00:00:00","Amount":0.0},{"Date":"2013-08-23T00:00:00","Amount":0.0},{"Date":"2013-09-09T00:00:00","Amount":0.0},{"Date":"2014-08-04T00:00:00","Amount":0.0},{"Date":"2014-08-11T00:00:00","Amount":30.0},{"Date":"2014-08-11T00:00:00","Amount":66.0},{"Date":"2014-08-11T00:00:00","Amount":85.0},{"Date":"2014-09-02T00:00:00","Amount":0.0},{"Date":"2014-12-16T00:00:00","Amount":0.0},{"Date":"2015-01-09T00:00:00","Amount":0.0},{"Date":"2015-02-10T00:00:00","Amount":14.0},{"Date":"2015-02-10T00:00:00","Amount":16.0},{"Date":"2015-02-10T00:00:00","Amount":43.0},{"Date":"2015-02-10T00:00:00","Amount":130.0},{"Date":"2015-02-10T00:00:00","Amount":130.0},{"Date":"2015-02-10T00:00:00","Amount":250.0},{"Date":"2015-02-10T00:00:00","Amount":640.0},{"Date":"2015-02-23T00:00:00","Amount":0.0},{"Date":"2015-02-25T00:00:00","Amount":0.0},{"Date":"2015-02-25T00:00:00","Amount":0.0},{"Date":"2015-03-26T00:00:00","Amount":0.0},{"Date":"2015-05-21T00:00:00","Amount":0.0}]" 

Я пытался найти скрытые символы с помощью html_entities и html_entity_decode и не нашли. Я также подтвердил использование mb_detect_encoding, что строка содержит все символы ASCII.

Я просто попытался следующее:

var_dump(json_decode(strval($a), true)); 

Результат был NULL, и ошибка декодирования была ошибка синтаксиса.

Что любопытно, var_dump на ($ а) дает мне количество символов в 4649, тогда как STRLEN ('[(„Дата“ ....) строки сама по себе дает количество символов 2789 ...

Answer 1

Благодаря все в вашей помощи я решил эту загадку!

Когда строка JSON была возвращена из базы данных Infusionsoft, все кавычки сохранялись как $ quot; а не как двойные кавычки.

Я нашел это, сохранив строку в TXT-файле (используя fopen, fwrite и fclose) и открыв файл с помощью текстового редактора.Я понял, что мне нужно будет посмотреть файл с шестнадцатеричным редактором (как рекомендовал Райан - я думаю, что это его имя, он удалил свой комментарий, содержащий предложение, так что я не уверен), но получается это не было необходимо. Вот то, что данные выглядели как в файле:

[{"Date":"2012-09-07T00:00:00","Amount":0.0},{"Date":"2012-09-07T00:00:00","Amount":41.0},{"Date":"2012-09-07T00:00:00","Amount":64.0},.... 

Чтобы удалить кавычки, которые я использовал htmlspecialchars_decode() на строке, а затем смог успешно передать строку в json_decode. Вот код:

$a = $conDat['_PMSChargeItems']; 
$b = htmlspecialchars_decode($a); 
$c = json_decode($b); 

Еще раз спасибо за ваши полезные комментарии и ответы!

Answer 2

EDIT

вы звоните json_decode на массив, который не JSon закодированной, вам нужно вызвать json_decode на строку, json_encoded, то есть элемент «_PMSChargeItems» в $ а

Это кажется к работе:

$a = '[{"Date":"2012-09-07T00:00:00","Amount":0.0},{"Date":"2012-09-07T00:00:00","Amount":41.0},{"Date":"2012-09-07T00:00:00","Amount":64.0},{"Date":"2012-09-11T00:00:00","Amount":80.0},{"Date":"2012-09-11T00:00:00","Amount":474.0},{"Date":"2012-09-19T00:00:00","Amount":82.0},{"Date":"2012-09-19T00:00:00","Amount":125.0},{"Date":"2012-09-19T00:00:00","Amount":127.0},{"Date":"2012-09-19T00:00:00","Amount":174.0},{"Date":"2012-09-19T00:00:00","Amount":343.0},{"Date":"2012-09-19T00:00:00","Amount":618.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-19T00:00:00","Amount":1122.0},{"Date":"2012-09-27T00:00:00","Amount":0.0},{"Date":"2012-10-02T00:00:00","Amount":0.0},{"Date":"2012-10-02T00:00:00","Amount":0.0},{"Date":"2012-10-10T00:00:00","Amount":0.0},{"Date":"2012-11-07T00:00:00","Amount":0.0},{"Date":"2012-11-19T00:00:00","Amount":64.0},{"Date":"2012-12-21T00:00:00","Amount":0.0},{"Date":"2013-02-01T00:00:00","Amount":0.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":470.0},{"Date":"2013-02-01T00:00:00","Amount":625.0},{"Date":"2013-02-01T00:00:00","Amount":625.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-01T00:00:00","Amount":679.0},{"Date":"2013-02-13T00:00:00","Amount":0.0},{"Date":"2013-02-18T00:00:00","Amount":0.0},{"Date":"2013-02-25T00:00:00","Amount":65.0},{"Date":"2013-02-25T00:00:00","Amount":85.0},{"Date":"2013-03-11T00:00:00","Amount":0.0},{"Date":"2013-03-14T00:00:00","Amount":0.0},{"Date":"2013-03-14T00:00:00","Amount":0.0},{"Date":"2013-03-20T00:00:00","Amount":240.0},{"Date":"2013-06-12T00:00:00","Amount":0.0},{"Date":"2013-07-23T00:00:00","Amount":0.0},{"Date":"2013-07-26T00:00:00","Amount":0.0},{"Date":"2013-08-23T00:00:00","Amount":0.0},{"Date":"2013-09-09T00:00:00","Amount":0.0},{"Date":"2014-08-04T00:00:00","Amount":0.0},{"Date":"2014-08-11T00:00:00","Amount":30.0},{"Date":"2014-08-11T00:00:00","Amount":66.0},{"Date":"2014-08-11T00:00:00","Amount":85.0},{"Date":"2014-09-02T00:00:00","Amount":0.0},{"Date":"2014-12-16T00:00:00","Amount":0.0},{"Date":"2015-01-09T00:00:00","Amount":0.0},{"Date":"2015-02-10T00:00:00","Amount":14.0},{"Date":"2015-02-10T00:00:00","Amount":16.0},{"Date":"2015-02-10T00:00:00","Amount":43.0},{"Date":"2015-02-10T00:00:00","Amount":130.0},{"Date":"2015-02-10T00:00:00","Amount":130.0},{"Date":"2015-02-10T00:00:00","Amount":250.0},{"Date":"2015-02-10T00:00:00","Amount":640.0},{"Date":"2015-02-23T00:00:00","Amount":0.0},{"Date":"2015-02-25T00:00:00","Amount":0.0},{"Date":"2015-02-25T00:00:00","Amount":0.0},{"Date":"2015-03-26T00:00:00","Amount":0.0},{"Date":"2015-05-21T00:00:00","Amount":0.0}]';
