解析 BBCode 样式标签以访问标签名称和包含的文本
我正在尝试解析一些文本，例如：
$text = "Blah blah [a]findme[/a] and [b]findmetoo[b], maybe also [z]me[/z].";
我现在拥有的是：
preg_match_all("/[*?](.*?)[\/*?]/", $text, $matches);
不幸的是，这不起作用。
有什么想法如何解析、返回节点键和相应的节点值吗？
I'm trying to parse some text for example:
$text = "Blah blah [a]findme[/a] and [b]findmetoo[b], maybe also [z]me[/z].";
What I have now is:
preg_match_all("/[*?](.*?)[\/*?]/", $text, $matches);
Which doesn't work unfortunately.
Any ideas how to parse, return the node key and the corresponding node value?

首先，如果您不将
()放在*?周围，则您与标签名称不匹配，其次，使用[*?]将匹配多个[直到您想要在内部匹配的]，因此您应该执行[(.*?)]和[ \/(.*?)]您必须尝试以下方法：
这不能保证有效，但会让您更接近。
你也可以这样做：
然后 foreach 结果递归循环直到 preg_match_all 返回 false，这是一种可能的嵌套方式。
Well firstly by you not putting
()around your*?your not matching the tag name, and secondly, using[*?]will match multiple[until the]where you want to match inside, so you should be doing[(.*?)]and[\/(.*?)]You would have to try something along the lines of:
this is not guaranteed to work but will get you closer.
you could also do:
and then foreach result loop recursively until preg_match_all returns false, that's a possible way how to do nesting.
为了匹配相同的标签，您需要一个反向引用：
这假设没有嵌套，如果您需要嵌套，请告诉我。
顺便说一句，我不知道你要如何处理这个 bbcode 风格的工作，但通常你会想要使用 preg_replace_callback() 来处理此类文本的内联修改，使用与上面类似的正则表达式。
In order to match the same tags, you need a backreference:
This assumes no nesting, if you need nesting then let me know.
Incidentally, I do not know what you are going to do with this bbcode style work, but usually you would want to use preg_replace_callback() to deal with inline modification of this sort of text, with a regexp similar to the above.
尝试：
这应该会为你指明正确的方向。
Try:
That should point you in the right direction.
我想出了这个正则表达式
((\[[^\/]\]).+?(\[\/[^\/]\]))。希望对你有用I came up with this regex
((\[[^\/]\]).+?(\[\/[^\/]\])). Hope will work for you我不是正则表达式猴子，但我认为您需要转义这些括号并创建组进行搜索，因为括号不会返回结果（括号会返回结果）：
希望这有效！
I'm no regex monkey, but I think you need to escape those brackets and create groups to search for, as brackets don't return results (parentheses do):
Hope this works!
即使 [b]“标签”未用 [\b] 反斜杠“b”关闭，您的第二个示例是否也应该被捕获。如果标签应该正确关闭，那么使用
这将确保开始和结束标签匹配。
Should your second example also be captured even though the [b] "tag" is not closed with the [\b] backslash 'b'. If tags should be properly closed then use
This will ensure that opening and closing tags match.
您可以尝试以下操作：
