What is the purpose of using do_shortcode in a PHP array?

The purpose of using do_shortcode in a PHP array is to allow the execution of shortcodes within the array's content. Shortcodes are placeholders that allow users to add dynamic content or functionality to their WordPress site. By using do_shortcode in a PHP array, you can ensure that any shortcodes present in the array's content are properly processed and executed.

// Example PHP code snippet using do_shortcode in a PHP array

$content_array = array(
    'title' => 'Example Title',
    'content' => 'This is an example content with a [shortcode]'
);

// Loop through the array and apply do_shortcode to the content
foreach ($content_array as $key => $value) {
    if ($key === 'content') {
        $content_array[$key] = do_shortcode($value);
    }
}

// Output the updated content array
print_r($content_array);
