你有没有试过启用'display_errors'并调查是怎么回事？ – J0HN

您能否更具体地了解错误？它何时发生，它是否会购买一条消息？运行时错误？ –

所以它只是说错误，没有给出任何线索在哪里？ – Alex

首先，你应该启用error_reporting。其次，你应该消毒使用mysql_real_escape_string（其他有害人们可以SQL inject）您的输入和第三，你应该用你的SQL查询后or die (mysql_error());，像这样：

$checkuser = mysql_query("SELECT username FROM users WHERE username='$username'") or die(mysql_error()); 
$checkuser1 = mysql_query("SELECT email FROM users WHERE email='$email'") or die(mysql_error());

如果你的SQL查询失败，你将看到正确的错误。
