将 .htaccess 重写规则转换为 PHP

Question

I have a WordPress site running on Pantheon, which uses nginx. Rewrite rules in the .htaccess files are ignored, so they need to be placed in wp-config.php instead. My regex skills are more or less nonexistent, and I need to convert these rewrite rules to PHP:

rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.xml$ "/index.php?xml_sitemap=params=$2" last;
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.xml\.gz$ "/index.php?xml_sitemap=params=$2;zip=true" last;
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.html$ "/index.php?xml_sitemap=params=$2;html=true" last;
rewrite ^/sitemap(-+([a-zA-Z0-9_-]+))?\.html.gz$ "/index.php?xml_sitemap=params=$2;html=true;zip=true" last;

Can anyone point me in the right direction?

Answer 1

Some comments.

First regarding the last flag, straight from the Apache documentation on rewrite :

The [L|last] flag causes mod_rewrite to stop processing the rule set. In most contexts, this means that if the rule matches, no further rules will be processed. This corresponds to the last command in Perl, or the break command in C. Use this flag to indicate that the current rule should be applied immediately without considering further rules.

Here are some more details on last .

Therefore, the pattern you would have to implement should look like a switch statement or a series of if-elseif s.

However, the Nginx wiki says using "if" is evil . It is suggested useing try_files instead.

This is what I use. Uses curl to proxy to a different URL path. Works with Drupal and Wordpress. https://github.com/mpaladino/pantheon-htaccess-rewrites
