php get parameter vs javascripts hash passed to php for session setting

everyone A very simple question, I'm working on a project web based The old way I used to direct different articles in my web projects is using PHP such

http://ift.tt/1A9UMHc

But I wanted to use something like

http://ift.tt/1JPv3DV instead of 
php?id=232

But, the only close solution, I got to this is using hashtag

window.location.hash;

In case you don't know the above function it get the hashtag from browser header. And thus you can pass it to PHP using JS as well to set session that like

    $_SESSION['articleid']="the hashtag"

Thus, when you open the page, it fist set the session, then load you the page Based on the article id

Ex.

Web.com/#1231231

Where javascript use window location hash and then pass it to PHP while loading

So, I have two questions

1- is using

 window.location.hash

with PHP Session, is good practice for this case? And secure? 2- is there any alternative, better practice or approach for my case

I'm not sure what search question to type or words, to get information about this.

So, if any of you need to know why I don't just use

PHP?id=1223

Because, in my project the user is in index.html And every button he/she clicks , it load contents into index.html So, if the user open an article, the article is loaded into the same

 index.html

But, then what if he/she want to share the article with another person Or if want to save it, for later?.

Thus, my solution was, to use

Window.Location.hash;

Read the hashtag, set the article id in session, load from article based on that session. If no hashtag, then just load the default

Please guide me. I see no problem with my approach.
