I keep getting undefined notices. I was going to see if you guys could show me the pro way of writing this code so it won't give me all those notices. I can get the undefined index thing to go away by doing this:

if (!isset($_REQUEST['DateOfBirth']) or $_REQUEST['DateOfBirth'])
   $_REQUEST['DateOfBirth'] = null;

Notice: Undefined index: DateOfBirth in /var/www/budget.fidelityreserves.com/html/clientbudget.php on line 156

Notice: Undefined offset: 2 in /var/www/budget.fidelityreserves.com/html/clientbudget.php on line 158

Notice: Undefined offset: 1 in /var/www/budget.fidelityreserves.com/html/clientbudget.php on line 165

Notice: Undefined offset: 2 in /var/www/budget.fidelityreserves.com/html/clientbudget.php on line 165

//Remove characters from DateOfBirth and split into array of three numbers
$date_arr = preg_split('/[\-\/ ]/', $_REQUEST['DateOfBirth']);
//If last number in array is a date field
if ( $date_arr[2] > 1900 ) {
        //reorder array with last number first
        $date = $date_arr[0].$date_arr[1].$date_arr[2];
        $_REQUEST['DateOfBirth'] = $date;
}
else {
        //else order array with first number first
        $date = $date_arr[1].$date_arr[2].$date_arr[0];
        $_REQUEST['DateOfBirth'] = $date;
}
