请帮忙 ！如何解决“非静态方法和此警告

Question

严格标准：非静态方法 PsychoDB::create() 不应在 www/stats/install/common.php 第 81 行静态调用

警告： 无法修改标头信息 - 标头已由 www/stats 中的（输出开始于 /home3/careersu/public_html/a1nomercy.tk/stats/install/common.php:81）发送/includes/class_session.php 第 236 行

这是81号线

$db = PsychoDB::create(array(
        'dbtype' => 'mysql',

    ));

Answer 1

PsychoDB 类的create 方法不是静态的。这意味着，而不是

public static function create($parameters) {

}

定义为

public function create($parameters) {

}

要解决这个问题，您可以使用第一个示例将方法转换为静态，但要小心。如果函数中有对类变量（$this->）的引用，您将再次遇到错误。由于我们不是通灵者，create 方法的内容仍然是个谜。

另一种选择是创建 PsychoDB 实例，然后使用实例的 create 方法。

$PsychoDB= new PsychoDB();

$db = $PsychoDB->create(array(
    'dbtype' => 'mysql',
    'delaystart' => true,
    'fatal'  => false,
));

当您处理完此错误后，第二个错误也将消失。只是 php 抱怨说，因为你已经输出了一些东西（错误消息），所以你不能使用 header 或 cookie 操作。
