为什么我会收到“缺少参数”警告?在我的 Boggle 解算器上?
几年前,有人在他们用 PHP 制作的 Boggle 求解器上发布了一些 PHP 代码。
如何查找可能的列表来自字母矩阵的单词 [Boggle Solver]
我一直在尝试让它工作,但我收到一个错误“警告:缺少 find_words() 的参数 7”,我已经知道它了,因为他似乎忘记将变量传递给函数。我一直在尝试让它发挥作用,但我似乎无法弄清楚,其他人可以做到吗?有可能有人有更奇特的东西吗?也许有什么东西可以追踪单词的路径?无论如何,如果有人能提供一些意见那就太棒了。

Some years ago here someone had posted some PHP code on a Boggle solver they made with PHP.
How to find list of possible words from a letter matrix [Boggle Solver]
I have been trying to get it to work but I get an error of "Warning: Missing argument 7 for find_words()" which I already know its because he seemed to forget to pass a variable into the function. I have been trying to get it to work but I cant seem to figure it out, can anyone else do it? Any chance anyone have something a little fancier? Maybe something that can track the path of the words? Anyways if anyone could have some input that would be awesome.

尝试将底部的
find_words
调用替换为:他只是忘记传递一个参数,代码看起来...可以接受。
Try replacing the
find_words
call at the bottom with:He just forgot to pass in one argument, the code looks... acceptable.
