PHP implements shake roll call program

Professor Lu’s needs:

<form name="input" action="#" method="post">
Password:<input  name="auth" value="<?php echo $_POST['auth']?>" type="password"><br>
Number:<input type="text" name="i"><br>
Work:<input type="text" name="id">
<input type="submit" value="Submit" /></form>
<?php
//echo md5("ojtest");
date_default_timezone_set('Asia/Shanghai');#设置时区
//$_POST['auth']=1;
//$_GET['test']=0;#是否为测试模式 默认为否
//echo md5('1');
function ini($num)
{
	$values=parse_ini_file('name.ini');#解析ini文件 格式 ： 姓名=学号
	return array_search($num,$values);#查找对应学号的姓名
}
if(md5($_POST['auth'])=='d49c880dd3d6e572ff1611f36b4ce04a')
{
error_reporting(0);
$I=$_POST['i'];#数量
for($k=0;$k<$I;$k++)
{
$r=mt_rand(1,52);
while($r==31)$r=mt_rand(1,52);
echo '<img src="'.$r.'.jpg"/><br>';//<img src="1.jpg" height=100 width=100 >
if($r>26)$r=3200+$r-26;
else $r=3100+$r;
echo $r."<br>".ini($r)."<br>";
$nm=ini($r);
//file_put_contents("./data.txt",$r);
//file_put_contents("./data.txt","\r\n");
$tim=date("y-m-d H:i:s");
$f=fopen("./data.xls", "a");
$id=$_POST['id'];
// $id;
if($id==NULL)fclose($f);
fwrite($f,"$r\t$nm\t$tim\t$id\r\n");#便于用excel打开
fclose($f);
}
}

?>

The above introduces the implementation of the shake roll call program in PHP, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
