我正在尝试创建一个注册系统，它会在用户注册后向用户发送激活码，但是我收到了注册表单错误，其中包含语法错误，意外情况和回声消息。 （T_ECHO在第133行的register.php中。

答案 0 :(得分：1)
在if条件
if (!$result_verify_email) { //if the Query Failed ,similar to if
($result_verify_email==false)
echo ' Database Error Occured ';
}
这一行($result_verify_email==false)应为
$result_verify_email==false;
更新：
在database_connection.php文件中取消注释您的凭据
DEFINE('DATABASE_USER', 'XXXX');
DEFINE('DATABASE_PASSWORD', 'XXXX');
DEFINE('DATABASE_HOST', 'localhost');
DEFINE('DATABASE_NAME', 'login');
或
DEFINE('DATABASE_USER', 'XXXX');
DEFINE('DATABASE_PASSWORD', 'XXXX');
DEFINE('DATABASE_HOST', 'localhost');
DEFINE('DATABASE_NAME', 'login');
或
相应地更改$dbc
$dbc = mysql_connect(XXXX, XXXX, localhost, login);
并将此行更改为此行，因为它即使没有数据也会尝试获取数据
if (!$result_verify_email) {
$result_verify_email==false;
echo ' Database Error Occured ';
exit();
}
