Button 在表视图中包含按钮

下面是我将一些值列为表的代码

if(is_array($employeeworkschedules)){
            $i=0;
        foreach($employeeworkschedules as $employeeworkschedule){
            $i++;

            $retString .="<tr><td>".$i."</td><td>" . $employeeworkschedule['date'] . "</td><td class='hexshifttype'>" . $employeeworkschedule['shiftTypeName'] . "</td><td class='hexemployee'>" . $employeeworkschedule['employeeFName'] . "</td><td class='hexworkschedule'>" . $employeeworkschedule['workScheduleCode'] . "</td></tr>";

        }
        }
        echo $retString;

if（is_数组（$employeeworkschedules））{
$i=0；
foreach（$employeeworkschedules作为$employeeworkschedule）{
$i++；
$retString.=''.i.'$employeeworkschedule['date'.'.'.$employeeworkschedule['shiftTypeName'.'.'.'$employeeworkschedule['employeeFName'.'.'$employeeworkschedule['workScheduleCode'.''；
}
}
echo$retString；

这是我的按钮代码

<button class="btn btn-outline-primary">
      <a class="edit mdi mdi-eye text-primary" href="<?php echo base_url()?>workschedule/Editemployeeworkschedule/<?php echo $employeeworkschedule['employeeWorkScheduleId'];?>">Edit</a>
</button>

如何将此按钮包含在上述给定代码中。如果（是数组（$employeeworkschedules））请帮助我{

if(is_array($employeeworkschedules)){
            $i=0;
        foreach($employeeworkschedules as $employeeworkschedule){


            $retString .="<tr><td>".$i."</td><td>" . $employeeworkschedule['date'] . "</td><td class='hexshifttype'>" . $employeeworkschedule['shiftTypeName'] . "</td><td class='hexemployee'>" . $employeeworkschedule['employeeFName'] . "</td><td class='hexworkschedule'>" . $employeeworkschedule['workScheduleCode'] . "</td><td <button class="btn btn-outline-primary">



            Edit
         </button> "</td></tr>";
$i++;
        }
        }
        echo $retString;

$i=0； foreach（$employeeworkschedules作为$employeeworkschedule）{

---

$retString.=''.i.'$employeeworkschedule['date']。'$employeeworkschedule['shiftTypeName']。'$employeeworkschedule['employeeFName']。'.$employeeworkschedule['workScheduleCode']。“您可以通过简单地创建一个来创建内部表格，方法是在..中写入按钮。我创建了它，但它显示了未定义的give$I++表的结尾您希望将按钮保留在表格中使用JSFIDDLE给出演示示例发生了相同的错误。语法错误，意外的'btn'（T_字符串）让我们。
