私はFirefoxとChromeに大きな問題を抱えています.私のコーディングはIEとsfariで完全に機能しています. firfox と chrome で機能しないのは、「bill_array」という 2 次元のセッション配列があることです。これらの 2 つのブラウザでは完全にクリアされません。xボタンを押すと.しかし、他の2つはうまくやっています.

<?php
//checking for perfect loging
session_start();
require ("connection.php");
if (!isset($_COOKIE['username']) && !isset($_COOKIE['password'])) {
    header('location:home.php');
    exit();
}
else {
    $user_name = $_COOKIE['username'];
    $user_pass = $_COOKIE['password'];
}

私は非常によく似た問題を抱えており、多くのヘッドバンギングの後、解決策を見つけました。誰かの役に立つかもしれないので、ここに投稿します。私の問題; サンプルコード

//set my variable
$_SESSION['variable'] = array(1,2);
// unset my variable
unset($_SESSION['variable']);
// check variable isset
if ( isset($_SESSION['variable']) ) {
   echo "isset";
} else {
    echo "not set";
}

IE、Chrome、Safari では、すべてのブラウザが「未設定」と報告されましたが、Firefox は「設定済み」と報告されました。私のドメインには 2 つの PHPSESSID Cookie がありました。例えば

  • domain.co.uk
  • www.domain.co.uk

www 以外の Cookie を削除すると (www を使用していたため)、すぐに他のブラウザーと同じ結果が得られました。解決策: PHPSESSID Cookie が 1 つだけ使用されていることを確認します。

これが他の人に役立つことを願っています。

配列全体の設定を解除するには、個々の変数の設定を解除する必要があります。
