我正在做一个程序，允许它的用户选择一些课程来创建。然而，我不知道如何实现循环这个动态文本框。这是我的第一个文件
<!DOCTYPE html>
<html>
<body>
<form action="k1levelselect.php" method="post">
How many lessons do you want to create? <input type="text" name="number" value=""><br>
<input type="submit" value="Submit">
</form>
<p>Type the number of lessons you want to create and click 'Submit'.</p>
</body>
</html>
这是我的k1levelselect.php，在用户输入一个数字并点击提交之后。

<?php
$noOfLesson = $_POST['number'];
for($noOfLesson=1;$noOfLesson<=10;){
echo "<td>";
echo 'k1level1.php' ;
echo "</div></td>";
}
?>
<div>
<a href="k1level1.php"><span>Lesson 1</span></a>

我如何编辑for循环，这样当用户输入7时，最多只会出现7个级别?
for ($i=1; $i < $noOfLesson ; $i++) {
echo "<div>";
echo "<a href='k1level$i.php'>Lesson $i</a>" ;
echo "</div>";
}
循环遍历每节课并使用计数器变量设置"关卡"。
像这样修复你的for循环
for($noOfLesson = 1; $noOfLesson < 10; $noOfLesson++) {
echo "<td>";
echo 'k1level'.$noOfLesson.'.php' ;
echo "</div></td>";
}
