<?php
$line = date("m.d.y") . "|" . $HTTP_POST_VARS['name'];
$line .= "|" . $HTTP_POST_VARS['news'];
$line = str_replace("\r\n","<BR>",$line);
$line .= "\r\n";
?>

Okay, I am reading a tutorial and i really dont get this part and they didnt explain it either

y is there 4 $line variables? i thought u could only have one
and y is there a "." before the "="

and whats "/r/n" etc...

Still the same
here is the code now

$password='zubair'
if($HTTP_POST_VARS['submit']) {
    if($HTTP_POST_VARS['password'] == $password) {
        if(!$HTTP_POST_VARS['name']) {
            echo "You must enter a name";
            exit;
        }
        if(!$HTTP_POST_VARS['news']) {
            echo "You must enter some news";
            exit;
        }

$password='zubair';
if($HTTP_POST_VARS['submit']) {
    if($HTTP_POST_VARS['password'] == $password) {
        if(!$HTTP_POST_VARS['name']) {
            echo "You must enter a name";
            exit();
        }
        if(!$HTTP_POST_VARS['news']) {
            echo "You must enter some news";
            exit();
        }
}

Just changed a couple of things.. Modified from my original post.

<?php
$password = 'zubair';
if($HTTP_POST_VARS['submit']) {
    if($HTTP_POST_VARS['password'] == $password) {
        if(!$HTTP_POST_VARS['name']) {
            echo "You must enter a name";
            exit;
        }
        if(!$HTTP_POST_VARS['news']) {
            echo "You must enter some news";
            exit;
        }
}
?>
