PHP Code problems...  please check for errors - or post better code

Last Modified: 2008-07-17
I'm having trouble with the following code working correctly.
It keeps showing the information in the "logged in" area without having to be logged in.
I don't have anyone else to check it for errors.
Can anyone help?


session_start(); // start session.

//Includes the header which also includes the variables file

// custom error function
function custom_die($errormsg) {
      print $errormsg;
} // end of custom_die function

// checks to see if the managers account number and password are set
if(!isset($manageracctnum) | !isset($manageracctpass)) {

// the below area is displayed when logged in......

logged in.....
<br />
This is display when the user has logged in.


// the above area is displayed when logged in...

// register account number and password as session variables

$db = mysql_connect($database_host, $database_username, $database_password) or die ($database_couldnotconnect);

$query = "SELECT managerpassword FROM $companytable_name WHERE companynumber = '$manageracctnum'";
$result = mysql_query($query) or custom_die($database_errorinquery);

$fetch_em = mysql_fetch_array($query);
$numrows = mysql_num_rows($query);

if($numrows != "0" & $managerpassword == $fetch_em["manageracctpass"]) {
            $valid_user = 1;
else {
            $valid_user = 0;
if (!($valid_user)) {
            session_unset();   // Unset session variables.
            session_destroy(); // End Session we created earlier.
// escape from php mode.


<div class="error">
Incorrect login information, please try again.
You must login to access the Manager Administration Area.
