Is there any problem with running HTML as PHP via .htaccess? such as security or best practices etc. was doing this to make URLs cleaner.

```
## run the following file types as php
Addhandler application/x-httpd-php .html .htm .rss .xml

```

Well ideally id like to have my URLs like 

```
localhost/blog/posts/view.php?id=64 

```

to be 

```
localhost/projects/bittyPHP/bittyphp/posts/view/id-64 

```

But having trouble accomplishing that without routing everything to one file and having PHP run determine the paths. I guess this is my real question
