PHP页面是空白的,源代码是空的

The PHP file is blank when I open it up in the browser. Also, when I open the source code, it is empty as well.

This is the tutorial I am following

And here is the code:

<?php

error_reporting(E_ALL ^ E_NOTICE);

?>
<!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Member System - Register</title>
</head>
<body>
<?php

if ($_POST['registerbtn']) {
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];
    $getconfirmpass = $_POST['confirmpass'];

    if ($getuser) {
        if ($getemail) {
            if ($getpass) {
                if ($getconfirmpass) {
                    if ($getpass === $getconfirmpass) {
                        if (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, ".")) {
                            require("./connect.php");

                            $query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0) {
                                $query = mysql_query("SELECT * FROM users WHERE email='$getemail'");
                                $numrows = mysql_num_rows($query);
                                if ($numrows == 0) {

                                    $password = md5 (md5("kjfiufj".$getpass."Fjf56fj"));
                                    $date = date("F d, Y");
                                    $code = md5(rand());

                                    mysql_query("INSERT INTO users VALUES (
                                        '', '$getuser', '$password', '$getemail', '0', '$code', '$date'
                                    )");

                                    $query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
                                    $numrows = mysql_num_rows($query);

    you have error on this line if (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, ".")) {

    it must be if ((strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, "."))) {

    alse the source code in the browser will show you the html code not the php php is server side so it's code is inside the server and browser can not see the php code
