我有以下html代码：

<tr>
  <td class="tablecontent" style="background-color: <?= $DATA_COLOR ?>;">
    <?= $oLanguage->getExpression('optherapy', 'revisionIndikation', 'Indication') ?>
  </td>
  <td class="tablecontent" style="background-color: <?= $DATA_COLOR ?>;">

这是基于类的php代码中的html部分。
现在我想通过读取表字段的内容重新显示从数据库中选择的结果。内容以逗号分隔的方式保存，例如。g、 ““3，7，9，16“（参见mysql query：如何使用concat\ws和coalesce正确地识别逗号分隔的结果值并将其重新转换为原始概念）。
基于php类的读取方法被定义为。。。

public function read() {

global $UNDEFINEDDATE, $oDatabase, $oLanguage;

$rev = $this->getLastCRFRevisionNr();

$qBaseline = ' SELECT ' .
             ' timestamp, ' . 
             blah blah blah,
             ' OP2RevisionIndikation, ' .
             blah blah blah
             ' FROM dat_optherapie ' .
             " WHERE patID = $this->iPatientID " .
             " and revision = $rev; ";

现在，读取这些数据的代码如下：

$haveOP1RevisionIndikation = explode(', ', $aBaselineData['OP1RevisionIndikation']);
$this->setOP1RevisionIndikation($haveOP2RevisionIndikation);

但是，这不足以在再次调用页面时以html显示输入的值。
我认为这最后两行是必要的。
有人知道怎么解决吗？
