steven --at-- acko --dot-- net pointed out that you can't make strip_slashes allow comments.
With this function, you can. Just pass <!--> as one of the allowed tags. Easy as pie: just
pull them out, strip, and then put them back.
<?php
function strip_tags_c($string, $allowed_tags = '')
{
$allow_comments = ( strpos($allowed_tags, '<!-->') !== false );
if( $allow_comments )
{
$string = str_replace(array('<!--', '-->'),
array('<!--', '-->'), $string);
$allowed_tags = str_replace('<!-->', '', $allowed_tags);
}
$string = strip_tags( $string, $allowed_tags );
if( $allow_comments ) $string = str_replace(array('<!--', '-->'),
array('<!--', '-->'), $string);
return $string;
}
?>
