code not executing?

[Ilovetopk]

When i submit my data via the form to my script script, it shows a blank page.  When i view the source, it shows my php code.

 

when i move the same script to the page with my form, it executes fine.  why would this be?  Is it something with permissions?

<?php
//enters connection details
require_once('config.php');

//connects to mysql database
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
	die('Failed to connect to server: ' . mysql_error());
}

//selects database
$db = mysql_select_db(DB_DATABASE, $link);
if(!$db) {
	die("Unable to select database");
}

//cleans posted login name
$login = $_POST['user'];

//gets email from server
$query="SELECT email FROM members WHERE login='$login'";
$result=mysql_query($query);
if(!$result) {
	print("Query Error: ".mysql_error());
}
$row = mysql_fetch_array($result);

//sets $email as their emqail address	
$email = $row['email'];

//generates random password
class utility {

    static $random = '';

    // generates a random password
    // By default of length 12 having special characters
    static function generate_password($length = 12, $special_chars=true) {
      $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
      if($special_chars) $chars .= '!@#$%^&*_-()';

      $password = '';
      for($i=0; $i<$length; $i++)
        $password .= substr($chars, self::generate_random_number(0, strlen($chars)-1), 1);
      return $password;
    }

    static function generate_random_number($min=0, $max=0) {
      // generate seed. TO-DO: Look for a better seed value everytime
      $seed = mt_rand();

      // generate $random
      // special thing about random is that it is 32(md5) + 40(sha1) + 40(sha1) = 112 long
      // hence if we cut the 1st 8 characters everytime, we can get upto 14 random numbers
      // each time the length of $random decreases and when it is less than 8, new 112 long $random is generated
      if(strlen(self::$random) < 8 ) {
        self::$random = md5(uniqid(microtime().mt_rand(), true).$seed);
        self::$random .= sha1(self::$random);
        self::$random .= sha1(self::$random.$seed);
      }

      // take first 8 characters
      $value = substr(self::$random, 0, ;

      // strip first 8 character, leaving remainder for next call
      self::$random = substr(self::$random, ;

      $value = abs(hexdec($value));
      // Reduce the value to be within the min - max range. 4294967295 = 0xffffffff = max random number
      if($max != 0) $value = $min + (($max - $min + 1) * ($value / (4294967295 + 1)));
      return abs(intval($value));
    }

figured it out, the file type was hidden from me, it was an html, not a php!  moved contents to php file, and wala!
