Once the sword is in hand, it depends on the swordsmanship of the person wielding the sword. This code can be further improved to make it more secretive. I just made a basic one, the details will depend on how you use it.
//Set time zone to China
date_default_timezone_set("PRC");
//Example output: 2010-03-06 Saturday 11:51:29 AM
//echo date("Y-m-d l H:i:s A");
$time_hour = date("H");
echo $time_hour;
$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4); //Only take the first 4 digits, so that only the highest priority language is judged. If you take the first 5 digits, en and zh may occur, which affects the judgment.
if($time_hour<13 || $time_hour>=18){
echo "<script>";<br>
echo "window.location.href='http://www.BkJia.com'";<br>
echo "</script>";
}elseif($time_hour>=8 && $time_hour<12 && preg_match("/zh-c/i", $lang)){
//Non-Chinese browser
echo "<script>";<br>
echo "window.location.href='http://www.BkJia.com'";<br>
echo "</script>";
}
else{
}
