using line breaks in meta tags

问题

I want to use line breaks in my website description meta tag. How do I do it, because if I see the source code it will still show <br/> only. Something like this I use in my code:

<meta name="description" content="<?php echo $gotAlias ?><br/>
abc: <?php echo $got_overallrating ?>.<br/>
<a href='www.abc.com'>Visit www.abc.com</a>
">

回答1:

Try "\n" instead of <br />, e.g. <?php echo "first line\nsecond line"; ?>;

回答2:

For use in AddThis meta content tagging, the \n is ignored. So it doesn't work.

回答3:

//META TAGS
add_action( 'wp_head', 'tws_output_meta_tags', 5 );
function tws_output_meta_tags() {
    echo '<meta name="author" content="content text" />'."\n";   

}
