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

[Chris]

good point on sprintf() - but assumes that I know the link will always 
have the bloginfo() as the variable.
 I was trying to generalise it so that, for several records in a text 
file, it would do the whole thing!
Thanks for suggestion
Does anyone know hwo to combine php functions and html using eval?? I 
would still like to know.
Chris
