Following is a practice code from a book titled "Head First PHP and sql" which I am studying. When I run sendemail.php in localhost sever I get two errors:
- Undefined variables Subject & text.
Both however were defined with the post array at the beginning. This code is about an HTML form that is part of PHP script, sticky form data and built-in PHP superglaobal variable $_Server['PHP_SELF']. Please see if I am missing something.

<?php
if(isset($_POST['Submit'])){
$from='elmer@makemelvis.com';
**$subject=$_POST['subject'];**
**$text =$_POST['elvismail'];**
$output_form =false;
if(empty($subject) && empty($text)){
echo 'You forgot the email subject and body text
<br/>';
$output_form =true;
}
if(empty($subject) && (!empty($text))){
echo 'You forgot the email subject<br/>';
$output_form =true;
}
if((!empty($subject)) && empty($text)){
echo 'You forgot the email body text<br/>';
$output_form =true;
}
if((!empty($subject)) && (!empty($text))){
$dbc = mysqli_connect('localhost', 'root',
'#######', 'elvis_store')
or die('Error connecting to Mysql Server.');
$query = "SELECT * FROM email_list";
$result = mysqli_query($dbc, $query)
or die ('Error querying database.');
while($row = mysqli_fetch_array($result)){
$first_name= $row['first_name'];
$last_name = $row['last_name'];
$msg= "Dear $first_name $last_name,\n $text";
$to= $row['email'];
mail( $to , $subject, $msg, 'From:'. $from);
echo 'Email sent to:' . $to.'<br>';
}
mysqli_close($dbc);
}
}// This will close the first if, which tells us
if the form was submitte.
else{
$output_form =true; //if the from's never
been submitted, we definitely need to show
it!
}
if ($output_form){/* This if statment
checks the $output_form variable
