Why do I “love” PHP or reassign variables?

  1. if ( is_numeric ($ email) &&! empty ($ email)) {
  2. $ email = $ this-> query ("SELECT email FROM users WHERE id =". $ email);
  3. if ($ email && mysql_num_rows ($ email)> 0) {
  4. $ email = mysql_fetch_row ($ email);
  5. $ email = $ email [0];
  6. }
  7. }

')
