.htaccess

For instance, if we have blog.php in the directory blog. And we want to redirect a URL like http://example.com/blog/123 to http://example.com/blog/blog.php?id=123. Then we need to do the URL rewriting.

/blog    ./blog.php

First of all, create a file called .htaccess in the directory that you want to rewrite.
Then, if you haven’t enabled the URL rewriting generally, write RewriteEngine On in your .htaccess file to enable URL rewriting.

Create rules

Then, in our .htaccess file, just simply type RewriteRule ^blog/([0-9]+) blog.php?id=$1.

Moreover, $1 means we take the first regexp as a variable.
