ThinkPHP6 routing parameters: Perfectly handle Chinese and special characters

In the ThinkPHP6 framework, when dealing with URL parameters, especially URL parameters containing Chinese and special symbols (such as punctuation marks), you often encounter parameter truncation problems. This article will explain in detail how to obtain these parameters in ThinkPHP6.

Question: Suppose a URL containing Chinese and special symbols: http://localhost/author-多米尼克•奥布莱恩.html , and the corresponding routing rule is Route::rule('/author-:name', 'index/index/author') . With the default settings, only "Dominic" can be obtained, while the "•O'Brien" part is truncated. How to get "Dominic O'Brien" in full?

Solution: The root cause of the problem is that the regular expression matching of the default routing rules is not comprehensive enough. [\w\-\•] can only match letters, numbers, underscores, minus signs and circled points. We need to modify the regular expression to support a wider character set.

Workaround: By customizing pattern property of the routing rules, we can specify more powerful regular expressions. The modified routing rules are as follows:

 Route::rule('/author-:name', 'index/index/author')->pattern(['name' => '[\p{L}\p{N}\-\•] ']);

[\p{L}\p{N}\-\•] regular expression is used here. \p{L} matches any Unicode letters, \p{N} matches any Unicode number. This is more comprehensive than previous expressions and is able to handle more types of characters, including Chinese and various special symbols.

If you need to support all Unicode characters, you can use more general expressions, but may affect performance. Therefore, it is recommended to choose the appropriate regular expression according to actual needs to balance the matching comprehensiveness and performance.

Through the above method, you can completely obtain URL parameters containing Chinese and other special characters in ThinkPHP6. It is crucial to choose the right regular expression, ensuring that all required characters can be matched and avoiding matching irrelevant characters to ensure the efficiency and correctness of the program.
