Difference between wordpress the_content() and get_the_content()

WordPress the_content() function is almost the same as get_the_content(), it’s defined as:

function the_content( $more_link_text = null, $strip_teaser = false) {
$content = get_the_content( $more_link_text, $strip_teaser );

/**
* Filters the post content.
*
* @since 0.71
*
* @param string $content Content of the current post.
*/
$content = apply_filters( 'the_content', $content );
$content = str_replace( ']]>', ']]>', $content );
echo $content;
}

From code above, the_content() function can not return the post content, however, it add a apply_filters and process “]]>”.Meanwhile, if you want to save the post content into a parameter, you should use get_the_content() function.
