RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ blog/?id=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ blog/?id=$1

Answer 1

Firstly check mod_rewrite is enabled on apache:
Then add the following to your .htaccess file
RewriteEngine On
RewriteRule ^/?blog/([a-zA-Z0-9_-]+)/$ /blog?id=$1 [L]
Also check AllowOverride All is given in the directory for this module in apache.
Following link can be useful:
AllowOverride for .htaccess on local machine giving 403 Forbidden

Answer 2

I spent almost two days last year chasing this one!
Many Linux distroes (at least Debian-based) prevent you from using a .htaccess file to override the Apache configuration files by stating AllowOverride None in the default config file.
You can change the line to AllowOverride All by editing /etc/apache2/sites-available/000-default
Hope this helps.

This is called Pretty URL's or SEO Friendly URLs, this can be achieved by several ways.
One way is doing everything yourself and modifying the .htaccess to look something like this:
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteRule ^users/(\d+)*$ ./profile.php?id=$1
RewriteRule ^threads/(\d+)*$ ./thread.php?id=$1
RewriteRule ^search/(.*)$ ./search.php?query=$1
Note that this requires your webserver to be Apache.
Other ways (which actually work somewhat the same) is by using PHP Frameworks which often have Routing with Pretty URL's implemented so you don't have to reinvent the wheel.
This is Laravel's approach of creating routes and pretty url's:
Route::get('/blog/{id}', function() {
// Do something
});
Take a look at Laravel: http://www.laravel.com. I really love this framework and its features.
Ruby on Rails has this implemented by default as well. But I assume you are not using it since you are programming PHP.
For a good tutorial explaining how to create Pretty URL's within PHP yourself take a look at this tutorial from TutsPlus: http://code.tutsplus.com/tutorials/using-htaccess-files-for-pretty-urls--net-6049
Hope I helped you! Good luck.
