使用PHP替换数据库字符串 - Use PHP to replace database string

Use PHP to replace database string

下面是我的代码:

            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>";

这是显示结果的页面的链接:

我如何修改我的php代码，以消除PlayerClass和PlayerRace从显示，所以如果他们没有选择一个类或种族，它显示为空?我不能在数据库中更改它，所以它必须在php显示

中替换

        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>";

您可以随意替换"   "
