PHP生成随机值

function randomkeys($length) {
    $key="";
    $pattern='1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ';
    for ($i=0; $i<$length; $i++){
        $key .= $pattern{mt_rand(0,35)};
    }
    return $key;
}

for ($i=0; $i < 10; $i++) {
    echo randomkeys(6);
    echo '<br>';
}

// ok
header(‘HTTP/1.1 200 OK’);

//设置一个404头:
header(‘HTTP/1.1 404 Not Found’);

//设置地址被永久的重定向
header(‘HTTP/1.1 301 Moved Permanently’);

//转到一个新地址
header(‘Location: http://www.example.org/’);
//文件延迟转向:
