我假设游戏逻辑是用Javascript编写的？您可以，您也可以使用，这对于大数据来说是一个更好的选择。

将post变量分配给变量，而不是使用它们

它会起作用的

   <?php
    $astate = $_POST['astate'];
    $wstate = $_POST['wstate'];
    $cstate = $_POST['cstate'];
    $gstate = $_POST['gstate'];
    $g2state = $_POST['g2state'];
    $g3state = $_POST['g3state'];
    $akcstate = $_POST['akcstate'];
    $tkcstate = $_POST['tkcstate'];
    $fkcstate = $_POST['fkcstate'];
   ?>
我想您在获取数据时遇到了问题

$\u POST['$astate']，如
$\u POST['astate']无需在post字段名称中输入$sing

下面的set cookie就是最好的例子


$astate = $_POST['astate'];

<?php
$expire=time()+60*60*24*30;
setcookie("astate", $astate, $expire);
?>



$astate=$\u POST['astate']；



尝试这样做，如果您有问题，请通知我
我认为您需要更改此选项：


$_POST['$astate'];
$_POST['$wstate'];
$_POST['$cstate'];
$_POST['$gstate'];
$_POST['$g2state'];
$_POST['$g3state'];
$_POST['$akcstate'];
$_POST['$tkcstate'];
$_POST['$fkcstate'];


为此：


$astate=$_POST['astate'];
$wstate=$_POST['wstate'];
$cstate=$_POST['cstate'];
$gstate=$_POST['gstate'];
$g2state=$_POST['g2state'];
$g3state=$_POST['g3state'];
$akcstate=$_POST['akcstate'];
$tkcstate=$_POST['tkcstate'];
$fkcstate=$_POST['fkcstate'];



查看setcookie.php，您以错误的方式接收提交的变量。要接收通过post提交的变量，请使用
$variable=$\u post['formVariable']
您还以错误的方式设置了cookie。要设置cookie，可以使用
setcookie（$cookiename、$cookievalue、$timetoexpire）。
因此，您的setcookie.php应该如下所示


    <?php
    $astate=$_POST['astate'];
    $wstate=$_POST['wstate'];
    $cstate=$_POST['cstate'];
    $gstate=$_POST['gstate'];
    $g2state=$_POST['g2state'];
    $g3state=$_POST['g3state'];
    $akcstate=$_POST['akcstate'];
    $tkcstate=$_POST['tkcstate'];
    $fkcstate=$_POST['fkcstate'];

    //Expire after 1 Hour for example
    $timetoexpire=time()+60*60;

    //set cookies
    setcookie("rqs1", $astate,$timetoexpire);
setcookie("rqs2", $wstate,$timetoexpire);
setcookie("rqs3", $cstate,$timetoexpire);
setcookie("rqs4", $gstate,$timetoexpire);
setcookie("rqs5", $g2state,$timetoexpire);
setcookie("rqs6", $g3state,$timetoexpire);
setcookie("rqs7", $akcstate,$timetoexpire);
setcookie("rqs8", $tkcstate,$timetoexpire);
setcookie("rqs9", $fkcstate,$timetoexpire);

if(isset($_COOKIE['rqs1'])){
    echo "$name : ".$_COOKIE['rqs1']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs1']))){
        echo "null \n";
        }

if(isset($_COOKIE['rqs2'])){
    echo "$name : ".$_COOKIE['rqs2']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs2']))){
        echo "null \n";
        }
if(isset($_COOKIE['rqs3'])){
    echo "$name : ".$_COOKIE['rqs3']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs3']))){
    echo "null \n";
    }

if(isset($_COOKIE['rqs4'])){
    echo "$name : ".$_COOKIE['rqs4']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs4']))){
    echo "null \n";
    }

if(isset($_COOKIE['rqs5'])){
    echo "$name : ".$_COOKIE['rqs5']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs5']))){
    echo "null \n";
    }

if(isset($_COOKIE['rqs6'])){
    echo "$name : ".$_COOKIE['rqs6']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs6']))){
    echo "null \n";
    }

if(isset($_COOKIE['rqs7'])){
    echo "$name : ".$_COOKIE['rqs7']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs7']))){
    echo "null \n";
    }

if(isset($_COOKIE['rqs8'])){
    echo "$name : ".$_COOKIE['rqs8']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs8']))){
    echo "null \n";
    }

if(isset($_COOKIE['rqs9'])){
    echo "$name : ".$_COOKIE['rqs9']." <br />\n";
    }
    elseif(!(isset($_COOKIE['rqs9']))){
    echo "null \n";
    }
    ?>



只是稍微更改了一下您的代码：\


<?php
  // `$_POST['$some_var']` doesnt create and assign a value to variable `$some_var`,
  // Its only check key `$some_var` exists in `$_POST` array and its if exists return its value
  // so doing it is WRONG
  $params = array( 'astate', 'wstate', 'cstate', 'gstate', 'g2state', 'g3state', 'akcstate', 'tkcstate', 'fkcstate' );

  foreach( $params as $param ) {
    $cookie = ( isset( $_POST[$param] ) ) ? trim( $_POST[$param] ) : null;
    $expire = ( time() + 3600 * 24 * 365 );
    if ( $cookie ) {
      // everything seems to be fine, now set the cookie
      setcookie( $param, $cookie, $expire, "/" );
    }
  }

  // now check here
  if ( isset( $_COOKIE["astate"] ) ) {
    // yes
  }
  else {
    // no
  }

  // OR

  foreach( $params as $param ) {
    if ( isset( $_COOKIE[$param] ) ) {
      echo $param." : ".$_COOKIE[$param]." <br />";
    }
  }
?>

（顺便说一句，您不需要else语句中的第二个if条件，因为它与第一个if条件正好相反）
我认为您需要这样做：
$astate=$\u POST['$astate']
你的php代码伤害了我的眼睛$name和$value有什么用？如果您必须使用$_cookie['cookiename']回显cookie access的值，为什么在字段名之前要签$sign？谢谢您告诉我我的错误：）下次要小心，因为我们为提问者提供了解决方案，没有问题：）在我尝试了您的建议后仍然给我空值，Junn，我也可能会通过javascript完成此操作，但是我仍然想弄清楚我在PHP中做错了什么，以便更好地理解PHP，为将来的项目等等。我很确定，除了设置COOKIE函数外，您还需要设置$\u COOKIE。谢谢您的关注。非常感谢。你的代码非常容易阅读，我实际上学到了一些东西！
