Wordpress PHP using global constants to avoid hard-coded values

Question

I am developing on a Wordpress website with my own php coding. So far I am using the Snippets plugin which I like most for adding PHP code to existing wordpress sites.

The only thing I would like to know is how i can use something like global constants to avoid hard-coded values. Because I am using the same values again and again. What is the best way?

Thank you for any help. best,

It is not recommended to create your own global variables on Wordpress (read this). But you you can achieve this by defining global variables.

function my_globals() {
        global $myglobals;
        // We define it as an array so you can store multiple values. If only needed one value you can directly set it 
        $myglobals = array();
        $myglobals['first'] = 'This is first content';
        $myglobals['second'] = 'This is second content';
}
add_action( 'after_setup_theme', 'my_globals' );

Now you can call your global using:

global $myglobals;
echo $myglobal['first'];
echo $myglobal['last'];
