Echo not displaying inside a div but worked outside of it - php

Question

I'm currently making a webpage and I have run in to some problems with echo being inside a div container.
My website is currently setup like this:
index.php has the header and a navigation pane on the left side. and there is a bodycontent div that will load in different pages depending on what is clicked.
I previously had the following code in my index.php right before my bodycontent div:
<?php
//set the variables
$username = isset($_POST['username']) ? $_POST['username'] : '';
$email = isset($_POST['email']) ? $_POST['email'] : '';
$password = isset($_POST['password']) ? $_POST['password'] : '';
$step = isset($_POST['step']) ? $_POST['step'] : '1';
//validation
if($step=='2'){
if($username == '' || strlen($username)==0){
echo 'username can not be blank<br/>';
}
if(filter_var($email, FILTER_VALIDATE_EMAIL) == false){
$errors[] = 'invalid email address<br/>';
}
if($password == '' || strlen($password)<=4){
$errors[] = 'password can not be blank or less than 4 characters<br/>';
}
$username=mysql_real_escape_string(trim($username));
$email=mysql_real_escape_string(trim($email));
$password=md5(mysql_real_escape_string(trim($password)));
//mysql queries
if(empty($errors)){
//do something
$query = "
INSERT INTO user
(email, username, password, user_level)
VALUES
('$email', '$username', '$password', '1')";
$result = mysql_query($query) or die ('error: '. mysql_error());
echo 'new user registered!';
$step='2';
}
else{
//error output
foreach($errors as $errors)
echo $errors;
$step='1';
}
}
if($step=='1'){
?>
I decided to move this piece of code in my registration.php page so the index.php looks cleaner for me.
However, ever since I moved the code from index.php to registration.php the echos are not displaying. If you need more code I will gladly post some more.. I don't want to overwhelm right now.

I noticed in your final foreach loop:
foreach($errors as $errors) is missing an opening bracket;
foreach($errors as $error) {
// instructions
}
