Question

我想问一下如何在HTML表格中显示来自php类的数据我尝试用HTML标签回显主题但由于某些原因我的代码无法识别html标签。

 public function getDataUser()
{
    $sql         = "SELECT ID, USERNAME , PASSWORD , EMAIL , PERMISSION_LEVEL FROM USERS";
    $this->_data = $this->_connection->query($sql);
    while ($row = $this->_data->fetch_assoc()) {
       echo $row["ID"] .$row["USERNAME"] . $row["PASSWORD"]. $row["EMAIL"]  . $row["PERMISSION_LEVEL"];
    echo"<br />";
    }
    return $this->_data;
}

此br标签不起作用。

Answer 1

当您返回数据时，您可能只想测试收到的数据：那么你可以使用print_r（在＆lt; pre＆gt;标签之间）：

public function getDataUser()
{
    $sql         = "SELECT ID, USERNAME , PASSWORD , EMAIL , PERMISSION_LEVEL FROM USERS";
    $this->_data = $this->_connection->query($sql);
    while ($row = $this->_data->fetch_assoc()) {
echo "<pre>";
print_r($row);
echo "</pre>";
    }
    return $this->_data;
}

Answer 2

试试这个

public function getDataUser()
{
    $sql = "SELECT ID,USERNAME,PASSWORD,EMAIL,PERMISSION_LEVEL FROM USERS";
    $this->_data = $this->_connection->query($sql);
    while ($row = $this->_data->fetch_assoc()) {
      //do print_r() to check wether data is coming or not
      echo '<pre>';
      print_r($row);
      echo '</pre>';

      //or you can print directly value by $row['ID']." ".$row['USERNAME'] by this way
    }
    return $this->_data;
}

Answer 3

echo $row["ID"] .$row["USERNAME"] . $row["PASSWORD"]. $row["EMAIL"]  . row["PERMISSION_LEVEL"]. " <br>";
