致命错误：未捕获的异常“PDOException”和消息“SQLSTATE[HY093]：无效的参数编号：绑定变量的数量与 /opt/lampp/htdocs/project/log/user.php 中的标记数量不匹配”： 51 堆栈跟踪：#0 /opt/lampp/htdocs/project/log/user.php(51)：PDOStatement->execute() #1 /opt/lampp/htdocs/project/log/registration.php(9)： user->userRegistration(Array) #2 {main} 在第 51 行的 /opt/lampp/htdocs/project/log/user.php 中抛出 请帮帮我....

您在 SQL 上指定了 5 个参数：

:name,:username,:email,:password,:gender

但是你只绑定了3个：

$query->bindValue(':name',$name);
$query->bindValue(':email',$email);
$query->bindValue(':password',$password);
