I'm not sure why people are being so deliberately obtuse here...

What you are looking for is mod_rewrite, an apache module for URL rewriting.

In your .htaccess file (you might need to make it) put:

<IfModule mod_rewrite.c>
RewriteEngine on

RewriteRule ^blog/([0-9]+)/.*$ /blog.php?post=$1 [L]
</IfModule>

This means when you go to /blog/10/any-old-bit-of-text/ behind the scenes it is identical to if you visited /blog.php?post=10.

The ([0-9]+) bit is called a regular expression (or regex), and matches any number. The .* means match anything. The ^ anchors to the start of the query and the $ anchors to the end. slashes (/) are escaped as /.
