echo is not showing anything on output browser side

Question

This should be printed on output browser side:

$form = <<<EOT
<form action="register.php" method="POST">
First Name: <input type="text" name="name" /></br>
Last Name: <input type="text" name="lname" /></br>
Username: <input type="text" name="uname" /></br>
Email: <input type="text" name="email1" /></br>
Confirm Email: <input type="text" name="email2" /></br>
Password: <input type="password" name="pass1" /></br>
Confirm Password: <input type="password" name="pass2" /></br>
<input type="submit" value="Register" name="submit" />
</form>
EOT;
echo $form;

But there is nothing.

This is my full code, which I should have added in the first place.

<?php
    require("config.php");
?>
<?php
if(isset($_POST['submit'])){

    $email1 = $_POST['email1'];
    $email2 = $_POST['email2'];
    $pass1 = $_POST['pass1'];
    $pass2 = $_POST['pass2'];

    if($email1 == $email2) {
        if($pass1 == $pass2) {
    //All good. Nastavi broo.

        $name = mysql_escape_string($_POST['name']);
        $lname = mysql_escape_string($_POST['lname']);
        $uname = mysql_escape_string($_POST['uname']);
        $email1 = mysql_escape_string($email1);
        $email2 = mysql_escape_string($email2);
        $pass1 = mysql_escape_string($pass1);
        $pass2 = mysql_escape_string($pass2);

    }else{
      echo "Sorry, your password is not corrext.";
      exit();
    }
}else{
  echo "Sorry!";
}

$form = <<<EOT
<form action="register.php" method="POST">
First Name: <input type="text" name="name" /></br>
Last Name: <input type="text" name="lname" /></br>
Username: <input type="text" name="uname" /></br>
Email: <input type="text" name="email1" /></br>
Confirm Email: <input type="text" name="email2" /></br>
Password: <input type="password" name="pass1" /></br>
Confirm Password: <input type="password" name="pass2" /></br>
<input type="submit" value="Register" name="submit" />
</form>
EOT;
echo $form;

}
?>

I tested, the code is working fine, you an issue with something else (ensure you are writing this within php tags though.) — Shaher Jamal Eddin, Jan 04 '16 at 22:17
I had that one lined up too @Dagon but will give them the 5 min. benefit of the doubt. — Funk Forty Niner, Jan 04 '16 at 22:21
There's nothing wrong with your code, it's just "you". so, do respond to comments up here. — Funk Forty Niner, Jan 04 '16 at 22:26
place it outside your conditional statement after your last `}`. — Funk Forty Niner, Jan 04 '16 at 22:36
@Dagon Nope, wasn't it. It was indeed a bracing thing, which I caught ;-) gotta love IDE's *huh?!* — Funk Forty Niner, Jan 04 '16 at 22:55
Please [stop using `mysql_*` functions](http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php). [These extensions](http://php.net/manual/en/migration70.removed-exts-sapis.php) have been removed in PHP 7.

Your form will only appear once you click the submit button because it is set inside the if(isset($_POST['submit'])){...} conditional statement. Therefore, you need to move your last brace } above $form = <<<EOT.

} // it belongs here instead of below echo $form;
$form = <<<EOT
<form action="register.php" method="POST">
First Name: <input type="text" name="name" /></br>
Last Name: <input type="text" name="lname" /></br>
Username: <input type="text" name="uname" /></br>
Email: <input type="text" name="email1" /></br>
Confirm Email: <input type="text" name="email2" /></br>
Password: <input type="password" name="pass1" /></br>
Confirm Password: <input type="password" name="pass2" /></br>
<input type="submit" value="Register" name="submit" />
</form>
EOT;

echo $form;

?>

and make sure you are accessing it as http://localhost/file.php and not as c://file.php

EDIT:

Here's a rewrite:

<?php
require("config.php");
?>
<?php
if(isset($_POST['submit'])){

$email1 = $_POST['email1'];
$email2 = $_POST['email2'];
$pass1 = $_POST['pass1'];
$pass2 = $_POST['pass2'];

if($email1 == $email2) {
    if($pass1 == $pass2) {
//All good. Nastavi broo.

$name = mysql_escape_string($_POST['name']);
$lname = mysql_escape_string($_POST['lname']);
$uname = mysql_escape_string($_POST['uname']);
$email1 = mysql_escape_string($email1);
$email2 = mysql_escape_string($email2);
$pass1 = mysql_escape_string($pass1);
$pass2 = mysql_escape_string($pass2);


}else{
  echo "Sorry, your password is not corrext.";
  exit();
}
}else{
  echo "Sorry!";
}

} // brace for submit conditional

$form = <<<EOT
<form action="register.php" method="POST">
First Name: <input type="text" name="name" /></br>
Last Name: <input type="text" name="lname" /></br>
Username: <input type="text" name="uname" /></br>
Email: <input type="text" name="email1" /></br>
Confirm Email: <input type="text" name="email2" /></br>
Password: <input type="password" name="pass1" /></br>
Confirm Password: <input type="password" name="pass2" /></br>
<input type="submit" value="Register" name="submit" />
</form>
EOT;
echo $form;

?>

Passwords

I also noticed that you may be storing passwords in plain text. This is not recommended. If you intend on going LIVE with this, do read the following.

Use one of the following:

CRYPT_BLOWFISH
crypt()
bcrypt()
scrypt()
On OPENWALL
PBKDF2
PBKDF2 on PHP.net
PHP 5.5's password_hash() function.
Compatibility pack (if PHP < 5.5) https://github.com/ircmaxell/password_compat/
