如何在带有urlenocde的URL中用连字符(-)替换+ [英] How to replace + with hyphen (-) in URL with urlenocde

问题描述

我在数据库中用空格存储了产品名称.例如Bike 86，洗衣机等.
使用urlencode后，URL进入浏览器，如下所示

I have stored the product names in database with spaces. For example Bike 86, Washing Machine etc.
After using urlencode URL comes to browser as below

http://www.example.com/product.php?productname=Washing+Machine

但我想得到这样的

But I want to get it such like

http://www.example.com/prodcut.php?productname=Washing-Machine

如何更改将空格编码为连字符(-)而不是"+"符号的urlencode函数.

如果urlencode无法实现，那我该怎么办.


注意:请给我一些其他解决方案，而不是str_replace();

How can I change the urlencode function that it encode the space into hyphen(-) not into "+" sign.

If it is not possible with urlencode then how can I do that.


Note: Please give me some other solution rather than str_replace();

推荐答案

这要复杂得多.

URL中的+具有特殊含义. Web服务器会将其解释为空间.如今，将空间编码为十六进制形式的最佳做法被认为是最佳做法，例如http://www.example.com/product.php?productname=Washing%20Machine遵循RFC 3986标准，但是+将会存在很长一段时间，并且仍然受所有浏览器和服务器的支持.

您要用-替换+.您不能这样做(即使使用str_replace也是如此)，因为+表示与空格相同，而-表示不相同.就是-.

虽然仍然有可能，但是在PHP中却没有.您将需要配置Web服务器以重写任何-在查找文件之前它会看到空格的迹象.在Apache上，您很可能会在网站的根目录中创建一个名为.htaccess 的文件，该文件将包含以下内容:

It''s a bit more complicated than that.

The + in the URL has a special meaning. The web server will interpret it as a space. These days it is considered best practices to encode space in its hex form e.g. http://www.example.com/product.php?productname=Washing%20Machine which follows RFC 3986 standards, but the + will be around for a long time and is still supported by all browsers and servers.

You want to replace the + with -. You can''t do that (even with str_replace) because whereas + means the same thing as space, - doesn''t. It just means -.

It is still possible though, but not in PHP. You will need to configure the web server to rewrite any - signs that it sees to spaces before it looks for the file. On Apache you would most likely create a file called .htaccess in the root directory of your site and it would contain something like:

RewriteEngine on

# Replace the minus character in incoming URLs with a space.
RewriteRule ^([^-]*)-([^-]*-.*)
