用变量修改字符串 [英] modify string with variables

问题描述

您好，


我已经建立了一个多语言网站。语言由url中的变量

定义 - > L = EN。网址中可能有更多变量：

mydomain.com/site.php?l=en&item=5&name=foo，但l = en也可以是

仅变量。


由于各种原因，请求的URL保存在会话变量中。

现在我想知道，如果有人输入的语言不是不匹配我提供的任何

语言，我希望将它们重定向到一个告诉

他们语言不存在的页面。


链接不允许丢失任何可能的变量，我试图通过搜索''l =''和''&''来使用

preg_replace，但是因为我不确定

是多个变量，所以URL中并不总是''&''。有什么线索吗？


谢谢。

Hi there,

i''ve built a multi-langual site. Languages are defined by a variable
in the url -> ''l=en''. There can be more variables in the url:
mydomain.com/site.php?l=en&item=5&name=foo, but l=en can also be the
only variable.

The requested url is saved in a session variable for various reasons.
Now i wonder, if someone enters a language that doesn''t match any
language i provided, i want them to be redirected to a page which tells
them the language doesn''t exist.

The links aren''t allowed to lose any possible variables, i tried to use
preg_replace by searching ''l='' and ''&'', but since i''m not sure there
are multiple variables, there isn''t always a ''&'' in the URL. Any clues?

thanks.

当您的PHP由Web服务器启动时，超全局数组

clues?

When your PHP is started by the web server, the superglobal array

_GET

填充了在URL上输入的值。


在您的情况下，如果有''l = en''，那么将是一个

_GET
is filled with the values entered on the URL.

In your case, if there is a ''l=en'', then there will be a

_GET ['''']

，其值为''en''。


所以，设置一个包含所有允许语言的数组（对于

例如：

_GET[''l'']
with the value of ''en''.

So, set up an array containing all of the permissable languages (for
