伊茨已经站在了世界之巅page@MidhuT你的问题格式正确吗，因为它看起来像一个单独的文件，代码中的configuration.php和submit.php是什么？我使用configuration.php连接到db。我有一个表单，在提交该表单后，它会转到submit.php。它会将表单数据插入表中，并选择特定的用户数据，然后使用header将其传递到displa.php。请不要使用mysql_*函数它们已弃用，将不再在PHPTH的更高版本中使用。那么，如何从反馈中检索$sql=select*，其中mobile='.$\u SESSION[phone].'；resultUse可以使用PDO或mysqli_*函数。我个人更喜欢PDO，但您可以使用类似于mysql函数的mysqli函数。您可以参考mysqlithe中的一些指南。问题是标头没有正确地将while的结果传递给display.php
