如何替换破折号（-）而不是网址中的空格？

Question

I am using Yii2, I am trying to change Url spaces to dash(-) .

The browser I'm using puts plus(+) instead of spaces in Url, in default;

For example this sentence:

"how to replace dash instead of space"

changes to:

/mysite.com/how+to+replace+dash+instead+of+space

But I want put dash(-) instead of plus(+) like blow Url:

/mysite.com/how-to-replace-dash-instead-of-space

Answer 1

You can use the following rule in htaccess :

RewriteEngine on

#1If uri has spaces, convert them to hyphens and set an  env "hasspaces"
RewriteRule (.*)\s(.*) $1-$2 [N,E=hasspaces:yes]
#2if the env "hasspaces" is set, we will redirect spaces to hyphens 
RewriteCond %{ENV:hasspaces} yes
RewriteRule ^(.+)$ /$1 [L,R]

This will convert all spaces in uri to hyphens and redirect the url

• example.com/hello word

to

• example.com/hello-word

Answer 2

Before doing this Be sure because - (dash) is used in url routing convention by Yii2 and match with the upper case in action name

Controller Class Naming

Controller class names can be derived from controller IDs according to the following procedure:

Turn the first letter in each word separated by hyphens into upper case. Note that if the controller ID contains slashes, this rule only applies to the part after the last slash in the ID. Remove hyphens and replace any forward slashes with backward slashes. Append the suffix Controller. Prepend the controller namespace. The following are some examples, assuming the controller namespace takes the default value app\\controllers:

article becomes app\\controllers\\ArticleController; post-comment becomes app\\controllers\\PostCommentController; admin/post-comment becomes app\\controllers\\admin\\PostCommentController; adminPanels/post-comment becomes app\\controllers\\adminPanels\\PostCommentController. Controller classes must be autoloadable. For this reason, in the above examples, the article controller class should be saved in the file whose alias is @app/controllers/ArticleController.php; while the admin/post-comment controller should be in @app/controllers/admin/PostCommentController.php.
