How to Remove "index.php" from URLs in CodeIgniter?

CodeIgniter htaccess and URL Rewrite Issues

Problem:

For a beginner using CodeIgniter, removing "index.php" from URLs while accessing pages like "about" (e.g., "localhost/ci/about") remains elusive. Despite experimenting with configurations and searching for solutions, the desired functionality is still not achieved.

Answer:

To resolve this issue and clean up URL rewrites, follow these steps:

1. Configuration in application/config.php:

• Set $config['base_url'] to the actual URL of your CodeIgniter installation.
• Set $config['index_page'] to an empty string ''.
• Set $config['uri_protocol'] to 'AUTO'.

2. .htaccess in the root directory:

Create a .htaccess file in the root directory of your CodeIgniter installation with the following content:

RewriteEngine on
RewriteCond  !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/ [L,QSA]

3. Enabling the rewrite engine in Apache (if not already enabled):

• Run a2enmod rewrite to initiate the rewrite module.
• Edit /etc/apache2/sites-enabled/000-default and change all "AllowOverride None" to "AllowOverride All".
• Restart Apache using sudo /etc/init.d/apache2 restart.

After completing these steps, you should now be able to access your pages without the "index.php" in the URL. For example, "localhost/ci/about" should successfully load the "about_page.php" view.
