mod_rewrite将'_'替换为'-' [英] mod_rewrite replace '_' with '-'

问题描述

我几乎已经有了mod_rewrite规则，但是我已经陷进了:)

I'm almost there with a mod_rewrite rule, but I've caved in :)

我需要重写

country/[countryname].php 

到

country/[countryname]/

但是，[countryname]可能带有这样的下划线:'south_africa.php'，如果确实如此，我想将其替换为连字符:'south-africa/'

however, [countryname] may have an underscore like this: 'south_africa.php' and if it does I want to replace it with a hypen: 'south-africa/'

如果该国家/地区后面有数字，我也想匹配:从'france03.php'到'france/'

I also want to match if the country has numbers following it: 'france03.php' to 'france/'

这里是我的规则，几乎在这里，但是即使下划线后没有第二部分，它仍然会添加连字符.

Heres my rule, its almost there but its still adding a hyphen even if there is no second part after the underscore.

RewriteRule ^country/(.*)_(.*?)[0-9]*\.php$ country/$1-$2 [R=301,L]

因此当前"country/south_.php"变为"country/south-/"

so currently 'country/south_.php' becomes 'country/south-/'

有人可以帮我找到难题的缺失部分吗?谢谢.

Can someone please help me find the missing piece of the puzzle? Thanks.

推荐答案

尝试一下:

RewriteRule ^country/([^_]*)_([^_]*?)\d*\.php$ country/$1-$2 [R=301,L]

此规则将使用带有单个下划线的网址进行匹配-您需要使用其他规则来获得更多的下划线，否则就不使用.

This rule will match urls with a single underscore - you'll need a different rule for more underscores or none.

如果要确保$2仅包含字母并且不为空，请将([^_]*?)更改为([a-zA-Z]+).

If you want to make sure $2 contains only letter and isn't empty, change ([^_]*?) it to ([a-zA-Z]+).
