How to remove index.php and ?r= in Yii Framework

Do these 3 steps:

1. Enable Url re-writing on Apache.

2. Place .htaccess on root of your project

   RewriteEngine on
   
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   
   RewriteRule . index.php
   

In your configuration protected/config/main.php set showScriptName to false like this to your url manager components >> urlManager

'urlManager'=>array(
  'urlFormat'=>'path',
  'rules'=>array(
      '<controller:\w+>/<id:\d+>'=>'<controller>/view',
      '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
      '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
  ),
  'showScriptName'=>false,
)

1) enable your urlManager in protected>>config>>main.php by adding these line to the array:

    'urlManager'=>array(
        'urlFormat'=>'path',
        'rules'=>array(
            '<controller:\w+>/<id:\d+>'=>'<controller>/view',
            '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
            '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
        ),
  'showScriptName'=>false,
    ),

2) The .htaccess file should be in the site root in the same of index.php level and should be like that:

    RewriteEngine on

    # if a directory or a file exists, use it directly
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond $1 !^(index\.php)

    # otherwise forward it to index.php
    RewriteRule ^(.+)$ index.php?$1 [PT,L,QSA]

3) make sure that your Apache configuration AllowOverride All not None
