------解决方案--------------------
保存上一个随机数不就可以了啊

$temp=rand(10000, 9999900000000000);
echo $temp;
}
?>

<br /> /*如果你需要的是一组随机数,那么可以考虑将随机数存储在数组中<br /> 如果你的随机数,需要跨页面传送那么建议你存在全局数组SESSION中*/<br /> <?php session_start();<br /> $t=rand(1000,7000);<br /> $_SESSION[]=$t;<br /> print_r($_SESSION);<br /> ?><br />
