我正在查询作为资源输出的数据库，例如

$tracker=get_record("tracker_entries", "userid", $user, "course", $course->id, "unitid" , $unit);

输出为：

$tracker->obj;

我写了一个运行良好的循环。我正在努力解决的问题是将 $f 整数添加到资源中。即加入2个变量。

$tracker->obj.$f;

它将它们视为 2 个独立的回声，有人知道我如何加入变量以便输出

$tracker->obj1
$tracker->obj2
$tracker->obj3
$tracker->obj4

ETC

希望这是有道理的，这是我的代码

 $f=0;
 for($number=1;$number<6;$number+=1){
 for($i=0;$i<6;$i+=1){
 $f+=1;  
 $theunit = $unitx->pc.$f;
 $thetracker = $tracker->obj.$f;
 $feedback = $tracker->feedback.$f;
       if(!empty($theunit)){
          echo'<tr>
              <td class="pc" valign="top" valign="top" align="left" width="5%"><strong>'.$number.'.'.$i.'</strong> </td>
              <td valign="top" class="pc" align="left">'.$theunit.'</td>
              <td valign="top" class="pc" align="left">'.$feedback.'</td>
              <td valign="top" class="pc" align="center">'.$thetracker.'</td>
          </tr>';
      }
 }
 }

$tracker 的 var_dump（有点大）

使用标量

示例代码：

<?php
$obj = (object) 'ciao';
$obj->test1 = (object) 'test1';

$i = 1;

echo $obj->test1->scalar . PHP_EOL;

echo $obj->{'test'.$i}->scalar . PHP_EOL;

你的代码：

$theunit = $unitx->{'pc'.$f}->scalar;
$thetracker = $tracker->{'obj'.$f}->scalar;
$feedback = $tracker->{'feedback'.$f}->scalar;
