Wordpress php回声问题

Question

Im trying to filter out all of the tags inside a post in wordpress using strip_tags(). I set it up like this:

<?php
// The Query
echo date ("Y");
query_posts( 'p=10' );
// The Loop
while ( have_posts() ) : the_post();
$footertext = the_content(); 
echo strip_tags($footertext);
endwhile;
// Reset Query
?>

This doesn't seem to strip out the tags they way I expected.

Answer 1

Change the_content() to get_the_content().

the_content() is used to directly output the contents whereas get_the_content returns contents to be stored in variable for further processing.

$footertext = get_the_content();
