" || $row['zt']=="交易完成") echo "(<a href='###' onclick='return show_order({$row['id']});'>查看</a>)";?></td>

您好!这段代码是一个包含一个二维数组的PHP代码,该数组中包含了几个学生的信息,通过遍历数组,将学生的信息以表格的形式输出到HTML页面中。不过需要注意的是,代码中存在一些语法错误,可能会导致程序无法正常运行,例如:数组元素的末尾缺少了逗号,导致数组解析出错。以下是修改后的代码:
```php
<?php
$arr = array(
array(
'stu_no' => 2011211,
'name' => '张三',
'age' => 18,
'gender' => '男',
'height' => '175cm',
'weight' => '65kg',
'email' => 'admin@163.com',
'college' => '土木工程学院',
),
array(
'stu_no' => 2011212,
'name' => '李四',
'age' => 18,
'gender' => '男',
'height' => '168cm',
'weight' => '55kg',
'email' => 'admin@163.com',
'college' => '体育学院',
),
array(
'stu_no' => 2011213,
'name' => '王五',
'age' => 19,
'gender' => '男',
'height' => '165cm',
'weight' => '44kg',
'email' => 'admin@163.com',
'college' => '数学学院',
),
);

找出这串代码的错误并给出正确答案<!DOCTYPE html> <?php require_once('./conn.php'); $sql = "select * from result"; $result = $conn->query($sql); if ($result->num_rows>0){ while($row = $result->fetch_assoc()) { ?> <tr> <td><?php echo $row['id'] ?></td> <td><?php echo $row['name'] ?></td> <td><?php echo $row['age'] ?></td> <td><?php echo $row['result'] ?></td> <td> <button onclick="toUpdate(this)">修改</button> <button onclick="remove(this)">删除</button> </td> </tr> <?php } } $conn->close(); ?> <html> <head> <meta charset="utf-8" /> <link rel="stylesheet" type="text/css" href="css/style.css"/> <script type="text/javascript" src="js/index.js"></script> <title>学生成绩管理系统</title> </head> <body> <h1>学生成绩管理系统</h1> <table> <tr> <td><a href="insert.php"><button>添加</button></a></td> </tr> </table> </body> </html> <script type="text/javascript"> function remove(ele){ let id = ele.parentElement.parentElement.children[0].innerText; window.location.href="remove_server.php?id="+id; } function toUpdate(ele) { let id = ele.parentElement.parentElement.children[0].innerText; window.location.href = "./update.php?id="+id; } </script>
这段代码的错误是在 HTML 标签和 PHP 代码之间有一个空行,这可能会导致输出带有额外的空格或换行符。正确的代码如下所示:
```
<!DOCTYPE html>
<?php require_once('./conn.php');
$sql = "select * from result";
$result = $conn->query($sql);
if ($result->num_rows>0) {
while($row = $result->fetch_assoc()) { ?>
<tr>
<td><?php echo $row['id'] ?></td>
<td><?php echo $row['name'] ?></td>
<td><?php echo $row['age'] ?></td>
<td><?php echo $row['result'] ?></td>
<td>
<button onclick="toUpdate(this)">修改</button>
<button onclick="remove(this)">删除</button>
</td>
</tr>
<?php
}
}
$conn->close();
?>
<html>
<head>
<meta charset="utf-8" />
<link rel="stylesheet" type="text/css" href="css/style.css"/>
<script type="text/javascript" src="js/index.js"></script>

</head>
<body>
<h1>学生成绩管理系统</h1>
<table>

</tr>

</body>
</html>
<script type="text/javascript">
function remove(ele) {
let id = ele.parentElement.parentElement.children[0].innerText;
window.location.href="remove_server.php?id="+id;
}
function toUpdate(ele) {
let id = ele.parentElement.parentElement.children[0].innerText;
window.location.href = "./update.php?id="+id;
}
</script>
```
