PHPstorm打开网页时显示空白页面

Question

在写代码的时候遇到的问题，问ls了也已读不回
关联代码没有任何问题，只有点击注册时跳转页面有问题
以下是关联代码

<?php
include_once "header.php"
?>
<style type="text/css">
    .tb{
        text-align: center;
        width: 400px;
        border: 1px darksalmon solid;
        background-color: rgba(255, 182, 193, 0.8);
        border-collapse: collapse;
    }
    tr{
        border: 1px #00c4ff solid;
    }
    td{
        border: 1px #ff5900 solid;
    }
</style>
<form action="logincheck.php" method="post">
    <table class="tb" align="center">
        <tr>
            <td colspan="2">会员登录</td>
        </tr>
        <tr>
            <td>用户名</td>
            <td>
                <input type="text" name="username">
            </td>
        </tr>
        <tr>
            <td>密码</td>
            <td>
                <input type="password" name="password">
            </td>
        </tr>
        <tr>
            <td>确认密码</td>
            <td>
                <input type="password" name="okpassword" >
            </td>
        </tr>
        <tr>
            <td colspan="2" align="center">
                <input type="button" value="注册" onclick="window.location.href='registercheck.php'">
            </td>
        </tr>
    </table>
</form>
<?php

?>

<?php
include_once "footer.php"
?>

点击注册后显示空白界面

<?php
//获取用户提交的注册信息
$username=$_POST["username"];
$psw=$_POST["password"];
$psw1=$_POST["password1"];
if(strcmp($psw,$psw1)==0)
{
    $link=@mysqli_connect("127.0.0.1","root","root","student2001","3306");
//var_dump($link);
    if($link==false){
        die("数据库连接失败！".mysqli_connect_error());
    }
    //执行查找语句，查找表中有没有此用户
    $sql=<<<LM

select * from users where username="$username"

LM;
    $query=mysqli_query($link,$sql);
    if(mysqli_num_rows($query)>0)
    {
        echo "<script>alert('你输入的用户已存在，请继续输入')</script>";
        header("refresh:1;url=register.php");
    }
    else
    {
        //把输入的用户信息插入到数据库表中
        $sql1=<<<LM

insert into users (username,password) values("$username","$psw")

LM;
        $query=mysqli_query($link,$sql1);
        if($query==true)
        {
            echo "<script>alert('用户注册成功，请登录')</script>";
            header("refresh:1;url=login.php");
        }
    }
}
else
{
    echo "<script>alert('两次密码不相同，请继续输入')</script>";
    header("refresh:1;url=register.php");
}

求各位指点迷津/(ㄒoㄒ)/~~
