php - syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING

I have been staring at this code for hours now and I cannot figure out where my mistake is. I know this syntax error usually comes up because of some missing or out of place curly brace or some issue with single/double quotes and I'm not sure there is one anywhere in my code. I am only trying to fix my syntax right now so I can get the code to completely compile. Any help would be much appreciated. Here is my code:

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
 
 


 



function print_form() {
echo <<         


    
Please put your comments below.


Name:


Comment:




END;    

    }
function process_form() {


print "
adding comment...
";

$Name = $_POST['WholeName'];
$Comment = $_POST['Comment'];

    if( preg_match("^[a-zA-Z]+$", $Name)) {
        if( preg_match("^[a-zA-Z0-9]_\-\'[.?!]+$", $Comment)) {
            $sql = "insert into comments1 values ( 
           '$Name', 

           '$Comment')";
           $result = mysql_query($sql) or die("Mysql query failed");
      } else {
        print "invalid name";
        }
  } else {
print "invalid characters";
 }

}


$db = mysql_connect("", "", "");
if (!$db) {
   print "Error - Could not connect to mysql";
   exit;
}  

$er = mysql_select_db("");
if (!$er) {
  print "Error - Could not connect to comments1 database";

  exit;
}

if (isset($_POST['stage']) && ('process' == $_POST['stage'])) {
   process_form();
} else {
    print_form();
}

?>

Answer

Your problem is that you're not closing your HEREDOC correctly. The line containing END; must not contain any whitespace afterwards.
