解析错误:语法错误，意外的 T_ECHO [英] Parse error: syntax error, unexpected T_ECHO

问题描述

过去几天我一直在做一些事情，但是这段代码总是会引发意想不到的 T_ECHO.我的朋友们似乎找不到任何问题，而我正处于耐心的边缘.即使删除了嵌套的 while 循环，它仍然会引发错误，我切换到 while: endwhile;语法也是如此，我仍然得到它.我确信答案正盯着我的脸，但我可能看不到.

I've been working on something for the past few days but this one bit of code perpetually throws an unexpected T_ECHO. My friends can't seem to find anything wrong with it and I'm at the edge of my patience. Even with the nested while loop removed it still throws an error and I switched to the while: endwhile; syntax as well and I'm still getting it. I'm sure the answer is staring me in the face but I probably can't see it.

  while ($row = mysql_fetch_array($result, MYSQL_ASSOC)):        
            echo "<tr>";
              echo "<td>". $row["site_description"] ."</td>";
              echo "<td>". $row["url"] ."</td>";
              echo "<td><select>";
                while ($roar = mysql_fetch_array($categories, MYSQL_ASSOC)):
                  echo "<option value=\"". $roar["category"] ."\">". $roar["category"] ."</option>";
                endwhile;
              echo "</select></td>";
            echo "</tr>";
          endwhile;

推荐答案

您可以使用短标签来提高可读性并减少出错的可能性.

You could use short tags to make this far more readable and likely less error prone.

<?php while ($row = mysql_fetch_array($result, MYSQL_ASSOC)): ?>
    <tr>
        <td><?= $row["site_description"] ?></td>
        <td><?= $row["url"] ?></td>
        <td>
            <select>
            <?php while ($roar = mysql_fetch_array($categories, MYSQL_ASSOC)): ?>
                <option><?= $roar["category"] ?></option>
            <?php endwhile; ?>
            </select>
        </td>
    </tr>
<?php endwhile; ?>
