为每个不同的单元格创建不同的 id

我想为每个不同的出勤单元格创建一个不同的 id 和值。

 public function show() {
    $year  == null;
    $month == null;
    if(null==$year&&isset($_GET['year'])){
        $year = $_GET['year'];
    }else if(null==$year){
        $year = date("Y",time());  
    }          
    if(null==$month&&isset($_GET['month'])){
        $month = $_GET['month'];
    }else if(null==$month){
        $month = date("m",time());
    }                  
    $this->currentYear=$year;
    $this->currentMonth=$month;
    $this->daysInMonth=$this->_daysInMonth($month,$year);  
    $content='<div class="row row-centered"><div class="col-xs-6 col-centered">'.
                    $this->_createNavi().
                    '</div></div>'.
