PHP页面是空白的，源代码是空的
问题描述：
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);
if ($numrows == 1) {
$site = "http://localhost/PHP Projects/Member System";
$webmaster = "Askman <donotreply@askmanproducts.com>";
$headers = "From: $webmaster";
$subject = "Activate Your New Account!";
$message = "Thanks for regisntering. Click the link below to activate your account!
";
$message .= "$site/activate?user=$getuser&code=$code
";
$message .= "You must activate your account to login.";
if (mail($getemail, $subject, $message, $headers)){
$errormsg = "You have been registered. You must activate your account from the activation link sent to <b>$getemail</b>";
$getuser = "";
$getemail = "";
}
else
$errormsg = "An error has occured. Your activation email was not sent.";
}
else
$errormsg = "An error has occured. Your account was not created.";
}
else
$errormsg = "There is already a user with that email.";
}
else
$errormsg = "There is already a user with that username.";
mysql_close();
}
else
$errormsg = "You must enter a valid email address to register.";
}
else
$errormsg = "Your passwords did not match.";
}
else
$errormsg = "You must confirm your password to register.";
}
else
$errormsg = "You must enter your password to register.";
}
else
$errormsg = "You must enter your email to register.";
}
else
$errormsg = "You must enter your username to register.";
}
$form = "<form action='./register' method='post'>
<table>

<td</td>

答
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
