WordPress theme developers should use `wp_head()`, `wp_body_open()` and `wp_footer()` functions in their themes (read this for more information).

The new WordPress theme structure:
```
<html>
  <head>

    ..
    ..

    <?php wp_head(); ?>

  </head>
  <body>

    <?php wp_body_open(); ?>

    ..
    ..

    <?php wp_footer(); ?>

  </body>
</html>
```

Don’t forget backward compatibility.
```
if ( function_exists( 'wp_body_open' ) ) {
	wp_body_open();
} else {
	do_action( 'wp_body_open' );
}
```

I Think This is the best way for add wp_body_open(); function for backwards compatibility

Step 1 : Checked if function is exits, if not exits then make a function called wp_body_open();

Example:
```
if ( ! function_exists( 'wp_body_open' ) ) {
    function wp_body_open() {
        do_action( 'wp_body_open' );
    }
}
```
Then put the function after the body tag.

Example:
```
<html>
  <head>
 
    ..
    ..
 
    <?php wp_head(); ?>
 
  </head>
  <body>
 
    <?php wp_body_open(); ?>
 
    ..
    ..
 
    <?php wp_footer(); ?>
 
  </body>
</html>
```

How can I use this to my advantage as a plugin developer? How to make sure my code is included if the WP version is 5.2+ but the theme is older and/or does not include wp_body_open?

Here is a working solution suggested by @danieliser on this ticket answer.
```
<?php
add_action( 'wp_body_open', 'wpdocs_my_function' );
add_action( 'wp_footer', 'wpdocs_my_function' );

function wpdocs_my_function() {
    if ( doing_action( 'wp_body_open' ) ) {
        remove_action ( 'wp_footer', 'wpdocs_my_function' );
    }

    // do stuff.
}
```
This way if you want to include code from your plugin just after the body tag opened by a theme that is up to date with good practices, and if it’s not, your code gets included the old way with wp_footer.

Custom Theme Hooks

Many themes use their own custom actions at the beginning of body tag. They should consider migrating to the core wp_body_open action.

For backwards compatibility, when injecting custom code, theme developers can use conditional logic to hook to the right action
```
function custom_code() {
    return '';
}

if ( did_action( 'wp_body_open' ) ) {
    add_action( 'wp_body_open', 'custom_code' );
} else {
    add_action( 'custom_theme_hook', 'custom_code' );
}
```
