[wp-hackers] Using eval within Wordpress for a function mixed with html

[Jason Webster]

Why don't you just use sprintf?

$string = '<a rel="external nofollow" href="%s/juniors/mirror"><img 
src="/oldsite/images/junior/.thumbs/.mirror.jpg" alt="mirror.jpg" 
title="mirror.jpg" width="95%" /></a> <hr />';

$string = sprintf($string, get_bloginfo('wpurl'));

Done!
