special characters in php

I want to display some chemistry equations like 23Na40K (source).

This value is in my database. Now it's display like this $^{23}$Na$^{40}$K. I tried to use html_entity_decode(), utf8_decode(), stripslashes(). Nothing works for me. Please help me to resolve this.

I havent seen anyone mention these:
¹²³⁴⁵⁶⁷⁸⁹⁰

Which are some Unicode Characters which don't look as good as the Superscript Tags but, if you still want to use HTML entities here they are:
¹²³⁴⁵⁶⁷⁸⁹⁰

Heres a comparison

HTML Tags: <sup>23</sup>Na<sup>40</sup>K
<br>Or<br>
HTML Entities: &sup2;&sup3;Na&#8308;&#8304;K

You can use an Equation HTML generator and use it into your website.

Or, you can also use Latex for displaying full equation html.

This can be done with Superscript in HTML like this:

Output: 23Na40K

<sup>23</sup>Na<sup>40</sup>K
