How to remove "index.php" in codeigniter's path

To remove "index.php" from the URL in CodeIgniter, you can use the .htaccess file. Here's an example of how to do it:

1. Create a .htaccess file in the root of your CodeIgniter installation.
2. Add the following code to the .htaccess file:

Example of removing "index.php" in CodeIgniter path

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]

3. Make sure that the mod_rewrite module is enabled on your server. If not, contact your hosting provider to enable it.

4. Open the application/config/config.php file and set the $config['index_page'] variable to an empty string:

Example of setting the $config['index_page'] variable to an empty string

// Remove 'index.php' from URLs
$config['index_page'] = '';

Now, the "index.php" should be removed from your URLs and your CodeIgniter application should work as expected.

Note: This process applies to CodeIgniter 3. CodeIgniter 4 uses a different directory structure and routing configuration. This process may vary depending on your hosting provider and server configuration.
