Question

我有一部嵌入的电影,并试图建立一套能够让我看到用户以前到这里来的功能。如果他们这样做,就会伪造汽车。

the followig code does not work <?php function autoplay(){ if ($REMOTE_ADDR == "") { $ip = "no ip"; echo "true"; } else{ $ip = getHostByAddr($REMOTE_ADDR); echo "false"; } } ?>

任何建议

Answer 1

you could use a cookie that will be stored in the user s browser. session_start(); before everything else in the page, then setcookie( visited , yes ,$time+2592000); after that before loading the movie check if $_COOKIE[ visited ] == "yes"; and thats it. 2592000 are the seconds in a month. Paste this at the first line of your page:

<? session_start(); $loopif=($_COOKIE[ visited ]=="yes")?false:true;setcookie( visited , yes ,$time+2592000); ?>

然后,当用户事先访问时,当他打算这样做时,便会发生错失行为。

建立了两个职能,并参照了嵌入的汽车部分的自动作用。

function ipfunction() {

    $ip=$_SERVER[ REMOTE_ADDR ];

    $queryone = "SELECT * from sessions where ip= $ip ";
    $result = mysql_query($queryone);
    if (mysql_num_rows($result) == 0) {
        mysql_query("insert into `sessions` (`id`, `session`, `ip`) VALUES (  ,  , $ip )");
    } else if (mysql_num_rows($result) != 0) {
        echo "";
    }
}

function autoplay() {

    $ip=$_SERVER[ REMOTE_ADDR ];

    $queryone = "SELECT * from sessions where ip= $ip ";
    $result = mysql_query($queryone);
    if (mysql_num_rows($result) == 0) {
        echo "true";
    } else if(mysql_num_rows($result) != 0) {
        echo "false";
    }
}
