do_shortcode

The do_shortcode function in WordPress is used to execute shortcodes that are embedded within a post or page. When do_shortcode is called, it scans the content provided for any registered shortcodes and then executes them. This allows for dynamic content to be inserted into pages or posts without the need for extensive HTML or PHP coding.

Here's how it works:

1. The do_shortcode function takes a string of content as its parameter.
2. It scans the content for any registered shortcodes.
3. If it finds any shortcodes, it executes the corresponding shortcode functions and replaces the shortcode tags with the output of those functions.
4. The modified content, with the shortcodes executed, is then returned by the do_shortcode function.

Overall, do_shortcode is a useful tool for injecting dynamic content into WordPress websites without having to manually write complex HTML or PHP code.
