我想在多次列出的元素$dictionary="stdClass Object
(
[status] => 0
[environment] => Sandbox
[receipt] => stdClass Object
(
[quantity] => 1
[expires_date] => 2017-04-18 08:56:57 Etc/GMT
[is_trial_period] => false
[purchase_date] => 2017-04-18 08:51:57 Etc/GMT
[product_id] => com.1monthAuto.baseball
[original_purchase_date_pst] => 2017-04-18 01:51:58 America/Los_Angeles
[original_purchase_date_ms] => 1492505518000
[web_order_line_item_id] => 1000000034854560
original_purchase_date] => 2017-04-18 08:51:58 Etc/GMT
)
[latest_receipt] => MIIT6wYJKoZIhvcNAQcCoIIT3DCCE9gC
)";
preg_match('/.*\[latest_receipt\].*$/m', $dictionary, $matches);
$receipt = str_replace('[latest_receipt] => ', '', $matches[0]);
echo $receipt;
中取一个值，并将其与之前的JobNumberString进行比较，看它是否高出1位数？这可能吗？
实施例：
JobNumberString给出错误，因为这不比之前的值高1。
