By default, the index.php file will be included in your URL:
Example.com/index.php/news/article/my_article
You can easily remove it by using the. htaccess file to set some simple rules. The following is an example of using the "negative" method to redirect non-specified content:
HTML Copy Code Rewriteengine on
Rewritecond $!^ (index\.php|images|robots\.txt)
Rewriterule ^ (. *) $/index.php/$1 [L] Copy code
Note: If your project is not in the root directory, please change the above sentence to: rewriterule ^ (. *) $ index.php/$1 [L]
In the above example, any HTTP requests that can implement any non-index.php, images, and robots.txt are directed to index.php.

When index is in the root directory, you can create a new. htaccess file in the root directory where the index.php is located and use the following code:

HTML Copy Code Rewriteengine on
Rewritecond $!^ (index\.php|robots\.txt)
Rewriterule ^ (. *) $/index.php?/$1 [L] Copy code

When index.php is not in the root directory, you can create a new. htaccess file in the directory where index.php is located and use the following code:

HTML Copy Code Rewriteengine on
Rewritecond $!^ (index\.php|images|robots\.txt)
Rewriterule ^ (. *) $/path_to_app/index.php?/$1 [L] Copy code

Note Replace the Path_to_app with the directory where your index.php files are located. Suppose your index.php is placed under the tool subfolder of the root directory, you can write:

HTML Copy Code Rewriteengine on
Rewritecond $!^ (index\.php|images|robots\.txt)
Rewriterule ^ (. *) $/tool/index.php?/$1 [L] Copy code
