#Overview Overview

WordPress provide us two functions these are:

• the_ID()
• get_the_ID()

#the_ID() vs get_the_ID() the_ID() vs get_the_ID()

#the_ID() the_ID()

When you want to print the current post ID then use the_ID() function.

E.g.

<div class="post-<?php the_ID(); ?>">

here we have created a CSS class post-<current post ID>.

Note In this example I have not used any escaping function. Read more about sanitisation and escaping.

#get_the_ID() get_the_ID()

When you want to assign the current post id to the variable then you can use the get_the_ID() function.

E.g.

$post_id = get_the_ID();

Here we have assigned the current post id to the PHP variable $post_id.
