Question

这是我的代码：

            echo "<td>" . $row4['CMUSERID'] . "</td>";
            echo "<td>" . $row4['CMCLAS'] . "</td>";
            echo "<td>" . $row4['CMRACE'] . "</td>";
            echo "<td>" . $row4['CMGEND'] . "</td>";
            echo "<td>" . $row4['CMSTRE'] . "</td>";
            echo "<td>" . $row4['CMDEXT'] . "</td>";
            echo "<td>" . $row4['CMCONS'] . "</td>";
            echo "<td>" . $row4['CMWISD'] . "</td>";

如何修改我的PHP代码以从显示中消除PlayerClass和PlayerRace，所以如果他们没有选择一个类或种族，它会显示为空？我无法在数据库中更改它，因此必须在php显示中替换它

        echo "<td>" . $row4['CMUSERID'] . "</td>";
        echo "<td>";
             echo $row4['CMCLAS'] == "PlayerClass" ? "&nbsp;" : $row4['CMCLAS'];
        echo "</td>";
        echo "<td>";
             echo $row4['CMRACE'] == "PlayerRace" ? "&nbsp;" : $row4['CMRACE'];
        echo "</td>";
        echo "<td>" . $row4['CMGEND'] . "</td>";
        echo "<td>" . $row4['CMSTRE'] . "</td>";
        echo "<td>" . $row4['CMDEXT'] . "</td>";
        echo "<td>" . $row4['CMCONS'] . "</td>";
        echo "<td>" . $row4['CMWISD'] . "</td>";
