PHP中的回声和回声

Question

如何在php中回显下面的代码？

<a href="cust_room/assign_room.php?cust_id=<?php echo $row_customer['cust_id']; ?>">Assign Room</a>

我确实试过这个，但收到了错误。

echo "<a href=\"cust_room/assign_room.php?cust_id=<?php echo $row_customer['cust_id']; ?>\">Assign Room</a>";

Answer 1

尝试原因：echo在另一个回声中！使用concat来回显$row_customer['cust_id']

中的值

<?php echo "<a href=\"cust_room/assign_room.php?cust_id=".$row_customer['cust_id'] ."\">Assign Room</a>"; ?>

Answer 2

您无法在<?php

旁边使用<?php

尝试以下代码：

echo "<a href=\"cust_room/assign_room.php?cust_id={$row_customer['cust_id']}\">Assign Room</a>";

而不是：

echo "<a href=\"cust_room/assign_room.php?cust_id=<?php echo $row_customer['cust_id']; ?>\">Assign Room</a>";
