我正在创建一个表单，用户可以在其中输入联系人号码，并从数据库中提取数据。现在同一个电话号码可以属于多个人，这段代码只是一次获取一个人的详细信息。我应该做什么改变，以便它可以为所有人获取数据。
<?php

答案 0 :(得分：2)
问题在于，您始终使用$row = mysql_fetch_array($result)，因此您始终会重写$result和$row。所以当你上次调用它时，它会给你最后一个循环中的最后一行，并且在你的主循环中将终止。
试试这个：
$sql_search = "SELECT person_id FROM contactnumbers WHERE contact_number = " . mysqli_real_escape_string($name);
$id_result = mysqli_query($link, $sql_search);
while ($id_row = mysqli_fetch_array($id_result)) {
//....
}
1）避免sql注射
2）不要使用mysql函数。使用mysqli或PDO函数代替mysql_ *函数。
