php - 选择模具侧面然后滚动

编写一个程序，让用户选择骰子的数量拥有并打印一个具有适当最大值的随机卷值。

 print <<<HERE
 <h3>How many Face you want for your Dice</h3>
 <form action="" method="post">

 <input type="text" name="numFace" value="$numFace"/>
 <input type="submit" >

HERE;



$roll=rand(1,$numFace=filter_input(INPUT_POST, "numFace"));
print<<<HERE

  <p>you rolled a $roll.</p>
  <p>
  <img src="die$roll.png"
  alt=die="die: $roll"/>

  </p>

  HERE;
  ?>
 </body>
 </html>

我收到此警告：rand（）期望参数2为long，第21行的C：\ xampp \ htdocs \ numFaces.php中给出字符串
