新手刚上路，有些太奇葩的代码请忽略。。。

<code><?php echo"<form method=post >";
for($T=1;$T<br>";
}
    echo"<input type="submit" name="bt" value="生成图">";
echo"";


if(isset($_POST['bt']))
{
 $b=$_POST['stu'];
 
$image=imagecreate(600,600);
$backgroud=imagecolorallocate($image, 255, 255, 255);
$blue=imagecolorallocate($image, 0,0, 0);
$red=imagecolorallocate($image, 255, 0, 0);

for($i=47;$i</code>
