从 url 获取变量，无法回显完整字符串
我有一个动态网址，如下所示；
news/categories/s/23-brook-launch-new-zealand
“23”是文章 ID，“brook-launch-new-zealand”是文章标题。
当我这样做时：
echo $_GET['title'];
它只会回显：“brook”而不是完整的字符串。
我正在对我的网址使用 mod_rewrite，代码如下：
RewriteRule ^news/categories/([a-zA-Z]+)/([0-9]+)-([a-zA-Z]+) /news/view-article.php?category=$1&id=$2&title=$3 [NC]
如何回显完整字符串？
I have a dynamic url which looks like the following;
news/categories/s/23-brook-launch-new-zealand
the "23" is the article id and the "brook-launch-new-zealand" is the article title.
When I do:
echo $_GET['title'];
it only echos back: "brook" not the full string.
I am using mod_rewrite for my urls, code follows:
RewriteRule ^news/categories/([a-zA-Z]+)/([0-9]+)-([a-zA-Z]+) /news/view-article.php?category=$1&id=$2&title=$3 [NC]
How can I echo the full string?

您没有匹配可能的
-：因此完整的行将是：
You aren't matching against possible
-s:So the full line would be:
您的重写规则不支持破折号，请尝试以下一个：
Your rewrite rule does not support dashes try this one:
您用于匹配标题
([a-zA-Z]+)的正则表达式仅匹配一组字母 (az)，不包含破折号 (-) 符号。也许正则表达式的那部分应该是：(([a-zA-Z]+-?)+)那么你的重写规则将是：
The regex that you are using to match the title
([a-zA-Z]+)only matches a set of leters (a-z) and does not include a dash (-) symbol. Perhaps that part of the regular expression should be:(([a-zA-Z]+-?)+)Then your rewrite rule would be:
我想你可能想要：
在你的版本中，标题中只允许使用字母 (a-zA-Z)，因此正则表达式与破折号不匹配。上面的内容应该与破折号相匹配，并且还允许标题中出现数字（我怀疑您会希望允许）。
您甚至可能只想这样做：
...并允许标题中包含任何字符 - 您可以轻松摆脱这一点，因为标题是 URL 的最后部分。
I think you probably want:
With your version, only the letters (a-zA-Z) are allowed in a title, so the regex doesn't match the dashes. The above should match the dashes, and also will allow numbers in the title (which I suspect you will want to allow).
You may even simply want to do:
...and allow any character in the title - which you can easily get away with, since the title is the last portion of the URL.
