Php Can'；t使preg match在两个bookend字符串之间工作

我正在尝试获取两个

==Quotes==

之间的所有文本，但我在获取preg\u match以返回除null以外的任何内容时遇到问题，我的代码是：

preg_match('/== Quotes == .+ == Quotes/', $quotes_str, $matches);

您需要使用

s

修饰符，以便

也匹配新行。我还建议使用

preg\u match\u all

以防字符串中有多个

引号。哦，我还添加了一个捕获组来捕获
==quotes=
之间的值

我相信你可能需要这个：

preg_match_all('#== Quotes[^=]+==(.+?)== Quotes[^=]+==#su', $quotes_str, $matches);

或者这个：

preg_match_all('#\*\*== Quotes[^=]+==\*\*(.+?)\*\*== Quotes[^=]+==\*\*#su', $quotes_str, $matches);

不幸的是，WikiQuoteAPI没有为我提供一种直接针对报价的方法。实际数据本身的大小大约是这个的两倍。
preg_match_all('#\*\*== Quotes[^=]+==\*\*(.+?)\*\*== Quotes[^=]+==\*\*#su', $quotes_str, $matches);
