Answer 1

从表名中删除单引号

试试这个

$insertQuery = "INSERT INTO `tbl_users`(username,password,email,role) VALUES ('$username',sha1('$password'),'$email','registered')";

而不是

$insertQuery = "INSERT INTO 'tbl_users'(username,password,email,role) VALUES ('$username',sha1('$password'),'$email','registered')";

Answer 2

sql语句出错。

试试这个。

  $insertQuery = "INSERT INTO tbl_users (username,password,email,role) VALUES ('{$username}',sha1('{$password}'),'{$email}','registered')";

或者

$insertQuery = "INSERT INTO tbl_users (username,password,email,role) VALUES ('".$username."',sha1('".$password."'),'".$email."','registered')";

PHP不在MYSQL中编写数据
