我正在开发一个简单的应用程序，我可以在其中注册新用户。- 我在 apache 本地主机上使用带有 MySQL 的 SLIM PHP 框架 - 我有一个带有名为 tbl_user 的表的 MySQL 数据库。我已经使用 CURL 测试了我的 SLIM 实现——在客户端，我有三个名为 fname、电子邮件和密码的 EditView 字段以及一个注册按钮——它很简单，当用户单击注册按钮时，应该建立数据库连接并且新用户应该被添加到数据库中。注册很简单，无需任何检查。我将在解决此问题后实施。

请帮忙。我进行了很多搜索，但无法解决错误。

我收到以下错误：

当第一次创建 Slim 响应对象时，它设置了“text/html”的内容类型。

也许在您的 register() 方法中，您应该执行以下操作：

function register()
{
    $request = Slim::getInstance()->request();
    $response = Slim::getInstance()->response();
    $response['Content-Type'] = 'application/json; charset=utf-8';

    /* rest of your function here*/
}

你的错误是你没有这个文件来写错误 error_log(/var/tmp/php.log) [function.error-log]: failed to open stream: No such file or directory create using touch /var/tmp/php .log或通过 ftp
