mysql - PHP "else" and "if" on code for registration script -

i purchased script while ago (php/mysql) contains user registration form. script has area selection of gender (male or female). 2 options.

i want modify code allow selection of animal instead of sex. changed code in applicable places, , works great. problem is, displays animals 1 , 2, since initial code setup "male/female" selection (2).

i need find way code allow 15 animals instead of 2 results. here code. "profile_userinfo_gender1" , "gender2" call "gender" or "animal". should go "gender15". please help! thank you!

    if ($d->u->gender == 0) $d->gender = $this->lang('profile_userinfo_withoutinfo');     else {         if ($d->u->gender == 1) $d->gender = $this->lang('profile_userinfo_gender1');         else $d->gender = $this->lang('profile_userinfo_gender2');     } 

if ($d->u->gender == 0) $d->gender = $this->lang('profile_userinfo_withoutinfo'); else {     $total_gender = 15; //define total gender     for($i = 1;$i <= $total_gender;$i++){     if ($d->u->gender == $i) $d->gender = $this->lang("profile_userinfo_gender$i");      }     #add gender generic default.      if ($d->u->gender == $i) $d->gender = $this->lang("profile_userinfo_gender_default"); }
