OK, I used the global keyword and verified it (via print_r() ) in the
function, but I get nothing when I add print statements to
preg_replace_callback() :

$tagpatt = '/\{(\w+?)\}/';
$emesg = preg_replace_callback( $tagpatt,
create_function( '$matches',
'print_r($matches);print_r($info);$field=strtolower($matches[1]);return
$info[$field];' ),
$emesg );


It seems like p_r_c() can't do what I want, but it's seems to be
designed for just this type of backreference manipulation. Am I just
going about this the wrong way?
