【问题讨论】：
如果 fetch 失败，则返回 false。 但是当我执行 echo $row['email'] 时，我看到了电子邮件，它是正确的 您可以执行 print_r($row) 来验证返回的内容。 结果数组（[电子邮件] => john@mail.com [电话] => 123456123） 好吧，提交表单后，并没有显示其中包含的内容，但我不知道为什么。现在我编辑并显示所有代码，有人看到 waht 是错误的。我已经没有力气了 【参考方案1】：请使用array_key_exists() 函数检查您的变量中是否存在关键电子邮件和电话。
比如……
if (array_key_exists("email", $row["email"]))
if ($row['email'] == $email)
$errorMsg[] = "Adres e-mail jest już zajęty";
【讨论】：
警告：array_key_exists() 期望参数 2 是数组，字符串在 P:\xampp\htdocs\BTP\v4\register.php 中的第 36 行 if(array_key_exists($row["email" ], $row['phone']))以上是关于尝试访问 bool PHP 类型值的数组偏移量 [重复]的主要内容，如果未能解决你的问题，请参考以下文章
