The most common use of the shortcode is the following
```
<?php echo do_shortcode('[name_of_shortcode]'); ?>
```

Square brackets are required to echo the shortcode, not just the name of the shortcode.

echo do_shortcode( ' [my_shortcode] ' );

This is not clear in the example.

Example

// Making your custom string parses shortcode
$string = do_shortcode( $string );
// If your string has a custom filter, add its tag name in an applicable add_filter function
add_filter( 'my_string_filter_hook_tag_name', 'do_shortcode' );

To only allow specific shortcodes in comments:

add_filter('get_comment_text', function ($comment) {
    $finalComment = '';
    $allowed = ['snippet', 'quote'];
    $parts = preg_split('/(\[\/?\w+\])/', $comment, null, PREG_SPLIT_DELIM_CAPTURE);

    for ($i = 0; $i < sizeof($parts); $i++) {
        if (preg_match('/\[\w+\]/', $parts[$i])) {
            $shortcodeName = substr($parts[$i], 1, -1);
            if (in_array($shortcodeName, $allowed)) {
                $finalComment .= do_shortcode($parts[$i] . $parts[$i+1] . $parts[$i+2]);
                echo '++' . $parts[$i] . $parts[$i+1] . $parts[$i+2] . '++' . $i;
                $i += 2;
            } else {
               $finalComment .= $parts[$i];  
            }
        } else {
            $finalComment .= $parts[$i];
        }
    }
    return $finalComment;
});

An easy approach to defining and using shortcode.

function wpdocs_custom_shortcode ( $content = null ) {
	
	/*------Declare Variables------*/
	$part_1 = $part_2 = $part_3 = $part_4 = $part_5 = '';

	/*------Starting Portion------*/
	$part_1 .= '<div class="content-wrapper">';
	$part_2 .= '<h3 class="content-heading">Here is a heading</h3>';
	$part_3 .= '<div class="content-output">';

	/*------Ending Portion------*/
	$part_4 .= '</div>';
	$part_5 .= '</div>';
	
	/*------Return------*/
	return $part_1 . $part_2 . $part_3 . do_shortcode( $content ) . $part_4 . $part_5; 
}
/*------Register Shortcode------*/
add_shortcode( 'shortcode_name', 'wpdocs_custom_shortcode' );

Now you can use [shortcode_name]........ your content ........ [/shortcode_name] in your post editor.

Sometimes could be really useful to have a shortcode inside another:
```
function wpdocs_concat_shortcodes() {
    $output = 'My new shortcode';

    // Add the old shortcode to the new one
    return do_shortcode( '[wpdocs_box]' ) . $output;
    
}
add_shortcode( 'wpdocs_both_shortcodes', 'wpdocs_concat_shortcodes' );
```
