In general, If WordPress function start with
get_ such as
get_the_ID(), it will return results and it’s not going to echo anything. It’s useful when you have to manipulate the result before outputting or printing on the screen.
If WordPress function start with
the_ such as
the_ID(), WordPress will
echo the returned value and output will be displayed automatically on the screen.
When functions are used for internal logic
get_ function is used and when the result is needed to be displayed on the screen
the_ function is used.
What’s the difference between WordPress function
get_the_content() returns the requested post content. While the_content() echo the post content after applying the_content filter.
As get_the_content() does not pass the content through the the_content filter, the result of
get_the_content() will not auto-embed videos or expand shortcodes and more.
the_content() is the output of get_the_contnet() that will be passed through the_content filter and
echo at last.
