Undefined array key “HTTP_ACCEPT_LANGUAGE” 解决方法
We’re receiving this warning on PHP 8.2:
PHP Warning: Undefined array key "HTTP_ACCEPT_LANGUAGE" in /wp-content/plugins/countdown-builder/classes/countdown/CircleCountdown.php on line 182
I copied the change you made in SimpleCountdown.php to fix the same error, changing line 182 of CircleCountdown.php from this:
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);
to this:
$serverLang = '';if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
$serverLang = $_SERVER['HTTP_ACCEPT_LANGUAGE'];
}
$lang = substr($serverLang, 0, 2);
