Cannot access empty property

[boo_lolly]

i have no clue why this is happening. all the research i've done shows that this error occurs when coding in an OOP fashion. here's my error:

 

Fatal error: Cannot access empty property in /var/www/piratebeachhouse/validate.php on line 51

 

and here's my code

 

validate.php

<?php
    function valName($string)
    {
        $string = trim($string);
        if (!preg_match('/^[a-zA-Z ]+$/', $string)) {
            $_SESSION['error']['fullname'] = 1;
        }
    }

    function valParty($string)
    {
        $string = trim($string);
        if (!preg_match('/^[0-9]+$/', $string)) {
            $_SESSION['error']['numparty'] = 1;
        }
    }

    function valNights($string)
    {
        $string = trim($string);
        if (!preg_match('/^[0-9]+$/', $string)) {
            $_SESSION['error']['numnights'] = 1;
        }
    }

    function valDate($string)
    {
        $string = trim($string);
        if (!preg_match('/0?([1-9]?|1[0-2]?)[-\/.](0?[1-9]|[12][0-9]|3[01])[-\/.]20\d\d/', $string)) {
            $_SESSION['error']['date'] = 1;
        }
    }

    function valPhone($string)
    {
        $string = trim($string);
        if (!preg_match('/^1?[-.(]?(\d{3})[-.)]?(\d{3})[-.]?(\d{4})/', $string)) {
            $_SESSION['error']['phone'] = 1;
        }
    }

    function valEmail($string)
    {
        if (!preg_match('/^[A-Za-z0-9._-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}/', $string)) {
            $_SESSION['error']['email'] = 1;
        }
    }

   /* set session variable to show form has been submitted */
    if (isset($_POST)) {
        foreach ($_POST as $k -> $v) {           //<----   LINE 51
            $_SESSION['submitted'][$k] = $v;
        }
    }
    /* run validation functions */
    valName($_POST['fullname']);
    valPhone($_POST['phone']);
    valEmail($_POST['email']);
    valDate($_POST['arrivaldate']);
    valNights($_POST['numnights']);
    valParty($_POST['numparty']);

    /* redirect to index.php if erroneous input */
    if (count($_SESSION['error'] < 0)) {
        header('Location: index.php');
        exit;
    }

    $body .= 'Full Name: '. $fullname ."\n";
    $body .= 'Phone: '. $phone ."\n";
    $body .= 'Email: '. $email ."\n";
    $body .= 'Date: '. $date ."\n";
    $body .= 'Number of Nights: '. $numnights ."\n";
    $body .= 'Number in Party: '. $numparty ."\n";

    mail('test@mail.com', 'website form bookdate', $body);

    header('Location: index.php');
?>

 

as you may have noticed, this is a validation script that is called upon whenever someone submits a form from index.php. can anybody help?

change

foreach ($_POST as $k -> $v) {           //<----   LINE 51

to

foreach ($_POST as $k => $v) {           //<----   LINE 51

 

simple typo
