我希望使我的网址的搜索引擎优化更友好，但我真的有一个很难弄清楚是什么问题，因为我一直试图重写这个网址3天了。没有代码似乎不工作。
我有三个URL：

https://website.net/jobs/country.php?country=switzerland
https://website.net/jobs/state.php?country=switzerland&state=bern
https://website.net/jobs/state.php?country=switzerland&state=bern&city=17462

我想得到这些：

/jobs/switzerland 
/jobs/switzerland/bern/
/jobs/switzerland/bern/17462/

我似乎不明白问题出在哪里。这是我的第一个链接的代码，它显然没有做任何事情：

RewriteEngine on
RewriteRule ^jobs/country/([0-9]*)/?$ /jobs/country.php?country=$1 [L, QSA]

此外，这是一个论坛的一部分，所以有现有的重写，但我真的不知道如果他们影响任何东西，因为即使在一个新的htaccess我无法使它工作：

# Some hosts require RewriteBase to make RewriteRules work.
RewriteBase /

# Google SEO workaround for search.php highlights:
# Make this rule the first rewrite rule in your .htaccess!
RewriteRule ^([^&]*)&(.*)$ https://website.net/$1?$2 [L,QSA,R=301]
