如何将我的网站的网址名称更改为:www.example.com/user/panel.php更改为www.example.com/username/panel.php,其中“用户名”对于每个用户都是唯一的,并且对于每个登录名都是jsfiddle.net中数据库中用户的名称,他们可以帮我吗?
Personally I would not use .htaccess for this ( specifically )
that said most the time people do it this way
RewriteEngine On
RewriteRule ^users/([-a-zA-Z0-9_]+)/?$ index.php?user=$1 [L]
So if you had a url like
www.yoursite.com/users/someguy
Then it would pass it to apache ( and php ) as
www.yoursite.com/index.php?user=someguy
Then in PHP you could access it just using $_GET[user]
.
Now ignoring security concerns I may have ( you shouldn't rely on user input to tell who they are, they can lie about it) for this I would use what I call the URI method ( not URL ) a URI is an imaginary path. This is also the method employed by many MVC systems. So for this I will start with the URI
www.yoursite.com/index.php/users/someguy
Notice where the index.php is ( in the middle ). Then you do a .htaccess like this
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f #if not a real file
RewriteCond %{REQUEST_FILENAME} !-d #if not a real folder
RewriteRule ^(.*)$ index.php/$1 [L] #hide the index.php
So what this does is allow you to remove the index.php
giving you a url like this
www.yoursite.com/users/someguy
Which is what we want, and looks basically the same as the first case.
Then you cam use the $_SERVER['QUERY_STRING']
supper global which will give you everything past index.php
/users/someguy
And you can split that up, route it somewhere, do whatever you need to with it. Like this
$uri = array_filter( explode('/', $_SERVER['QUERY_STRING'] ) );
//$uri = [ 'users', 'someguy' ];
Now the reason I like this more, is it's more flexible and it lets you use the query string the ?var
part of the url for other stuff. ( like bookmarkable search forms ) ie. it feels less hacky because your not breaking the query parameters of a GET Request. Conversely, with the first method, if your .htaccess is sloppy you could make it were the query part of the URL is unusable on your site, and that just feels wrong to me.
It also easier to maintain, because it requires no further setup for additional pretty urls
For example: Say you want prettyfy your product. Using the first method you would have to go back to the .htaccess
add at least 1 more rule in:
RewriteEngine On
RewriteRule ^users/([-a-zA-Z0-9_]+)/?$ index.php?user=$1 [L]
RewriteRule ^products/(0-9_]+)/?$ index.php?product=$1 [L]
Possibly even more complex levels if you have product categories
RewriteRule ^produts/([-a-zA-Z0-9_]+)/(0-9_]+)/?$ index.php?category=$1&product_id=$2 [L]
After a wile you would wind up with dozens of rules in there, some of which may not be immediately clear as to what they do. Then you realize you spelled products
as produts
and have to start renaming things. It's just a mess later on.
Now using the second method you don't need to do any additional steps, besides routing it in your index page. You just put the url in
www.yoursite.com/products/123
And pull that stuff from the $_SERVER
array with no further messing with rewrite rules.
Here is a previous answer I did that outlines how to build a basic router.

Make sense.
