php - make checks with class and stop the script -


i created script change user's password, when checking continues.

class mudar_senha{      protected $page_return = 'mudar_senha';      private function encriptasenha($senha) {                  return base64_encode(pack("h*", sha1(utf8_encode($senha))));     }      private function query_senha(){          global $_lang;              $user_id = $_post['id_user'];              $q=new query;             $q                     ->select()                     ->from('`usuarios`')                     ->where_equal_to(                             array(                                     'id'=>$user_id                             )                     )                     ->limit(1)                     ->run();              if($q){                     $user=$q->get_selected();                      return $user['senha'];             }             else{               return                  alerta($_lang[165]);                 retornar(null,$this->page_return);                       die;                 }            }      private function verify_senha($senha){          global $_lang;              if($this->encriptasenha($senha) == $this->query_senha()){                  return true;                  }else{                   return                      alerta($_lang[203]);                     retornar(null,$this->page_return);                       die;                 }      }      private function verify_senhas(){          global $_lang;              if($_post['cpass1'] == $_post['pass1']){                  return true;              }else{                  return                      alerta($_lang[171]);                     retornar(null,$this->page_return);                       die;             }       }      private function verify_length($senha){          global $_lang;              switch($senha){                  case(strlen($senha) < 6) :                      return $_lang[206];                         die;                  case(strlen($senha) > 11):                  return                      alerta($_lang[205]);                     retornar(null,$this->page_return);                       die;                  default:                      return true;             }      }      private function verify_caracteres($senha){          global $_lang;              if(preg_match('/[\'\/~`\!@#\$%\^&\*\(\)_\-\+=\{\}\[\]\|;:"\<\>,\.\?\\\]/', $senha)){                  return                          alerta($_lang[204]);                         retornar(null,$this->page_return);                           exit;             }else{                  return true;              }      }      final public function _build(){          global $_lang;              if($this->verify_senha($_post['req1'])      == true);             if($this->verify_senhas()                   == true);             if($this->verify_length($_post['pass1'])    == true);             if($this->verify_caracteres($_post['pass1'])== true);                  $q=new query;                 $q                     ->update('usuarios')                     ->set(                             array(                                             'senha'         =>  $this->encriptasenha($_post['pass1']),                                             'pass_decode'   =>  $_post['pass1'],                             )                     )                     ->where_equal_to(                             array(                                     'id'=>$_post['id_user']                             )                     )                      ->limit(1)                     ->run();                          if($q){                              alerta($_lang[207]);                             retornar(null,$this->page_return);                          }else{                              alerta($_lang[165]);                             retornar(null,$this->page_return);                             exit;                         }            }   }   $q = new mudar_senha; $q->_build();

there 3 checks - correct password? - correct passwords? - password length - special characters

if denies checks script returns true, , _build function checks if changes continue normally.

all of die; statements after return statements. if you're going kill script, remove return statement beforehand since value won't matter anyway.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
