隐藏“www.blahblah.com/index.php”中的“index.php”

I want to hide "index.php" from "www.blahblah.com/index.php"? How to do that?

Please help, I've tons of codes now i'm planning to hide index.php from URL. I googled and found that you first need to create .htaccess file. But i don't know where to start it? and Should i need to create that file along with my projects? And what to type inside that file?

create .htaccess file then copy the code below change 'project_folder_name' of the folder of your project if your project is in the root folder just put '/'

<IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteBase /project_folder_name

        # Removes index.php from ExpressionEngine URLs
        RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
        RewriteCond %{REQUEST_URI} !/system/.* [NC]
        RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]

        # Directs all EE web requests through the site index file
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
