多个$ title =“ string”是什么意思？

Question

我是CakePHP的新手，我看到在多个函数中以完全相同的方式编写了多个$title="keycard"。这是什么意思？是否所有功能都已“添加”到钥匙卡中？

编辑：我在示例下方附上

function admin_keycard_index($aptNum){
$this->layout = 'admin_bootstrap';
$user = $this->Auth->user();
$title = "Keycards";
$currentTerm = $this->Timeframe->getCurrentTerm();
$this->Session->write('currentTerm',$currentTerm);
  $this->set('keycardState',$this->Keycard->getStates());
  $this->set('aptNum',$aptNum);
  $keycards = $this->Keycard->findAllByRoomNumber($aptNum);

function admin_reshall_index($buildingID = null) {
$this->layout = 'admin_bootstrap';
$user = $this->Auth->user();
$title = "Keycards";
$currentTerm = $this->Timeframe->getCurrentTerm();
$this->Session->write('currentTerm',$currentTerm);
$this->set('buildingID', $buildingID);
}
