这是什么类型的数据格式(冒号和分号分隔的条目)?

What kind of data format is this (colon and semicolon separated entries)?

我正在集成两个记录不完整的系统,在此过程中我遇到了一种我以前从未见过的奇怪数据格式。它以纯文本形式存储在数据库中,没有说明格式是什么以及如何处理它。

a:17:{s:2:"id";s:27:"145219921F990B11C39E7220000";s:16:"purchase_country";s:2:"no";s:17:"purchase_currency";s:3:"nok";s:6:"locale";s:5:"nb-no";s:6:"status";s:17:"checkout_complete";s:9:"reference";s:27:"145212221F990B11C39E7221000";s:11:"reservation";s:10:"2348226550";s:10:"started_at";s:25:"2014-04-04T10:40:55+02:00";s:12:"completed_at";s:25:"2014-04-02T10:41:11+02:00";s:16:"last_modified_at";s:25:"2014-04-02T10:41:11+02:00";s:10:"expires_at";s:25:"2014-04-16T10:41:11+02:00";s:4:"cart";a:4:{s:25:"total_price_excluding_tax";i:489500;s:16:"total_tax_amount";i:0;s:25:"total_price_including_tax";i:489500;s:5:"items";a:2:{i:0;a:10:{s:9:"reference";s:2:"68";s:4:"name";s:21:"1.OSO SUPER S 200LIT.";s:8:"quantity";i:1;s:10:"unit_price";i:695000;s:8:"tax_rate";i:0;s:13:"discount_rate";i:0;s:4:"type";s:8:"physical";s:25:"total_price_including_tax";i:695500;s:25:"total_price_excluding_tax";i:694000;s:16:"total_tax_amount";i:0;}i:1;a:10:{s:9:"reference";s:2:"68";s:4:"name";s:32:"1.OSO SUPER S 200LIT.

条目由冒号分隔的段组成:

现在,解析这个东西相当容易,但我经常对新的数据类型和它们奇怪的语法感到惊讶,我不确定我是否已经用我收集的少数数据样本涵盖了所有边缘情况’分析。有人熟悉这种格式吗?

看起来像 PHP 序列化。参见:http://www.phpinternalsbook.com/classes_objects/serialization.html
