lots of things:
1) variables in single-quoted strings aren't evaluated so you don't
need to escape the $ in $email
2) php uses . not + for concatenation.
3) try it like this:
eval('$email = $email_'.$i.';');
or
eval("\$email = \$email_$i;");
4) you can save yourself the trouble by using arrays as field names:
<input name="email[1]">
5) RTFM! that's what its there for.
