attempting to write to a new flat file gives flock error

Immyphp

its a simple problem, im sure you will laugh at me for asking,

in basic im running a program called wamp which runs php apache server and mysql, my ps is a vista 64 bit operating system

wamp requires i put all php and files into the www folder to run them through the wamp interface this all works fine

heres the dilema

when i attempt to write to a new flat file using php it gives me this error

Warning: flock() expects parameter 1 to be resource, boolean given in C:\wamp\www\bobscars\processorder.php on line 75

this is the php code in question

<?php
// create short variable names
$tireqty = $_POST['tireqty'];
$oilqty = $_POST['oilqty'];
$sparkqty = $_POST['sparkqty'];
$address = $_POST['address'];
$DOCUMENT_ROOT = $_SERVER['DOCUMENT_ROOT'];
$date = date('H:i, jS F Y');
?>

<html>

<head>

<title>Bob's Auto Parts - Order Results </Title>
</head>
<body>

<h1>Bob's Auto Parts</h1>
<h2>Order Results</h2>
<?php


echo "<p>Order Processed at ".date('H:i, jS F Y')."</p>";

echo "<p>Your order is as follows: </p>";

$totalqty = 0;

$totalqty = $tireqty + $oilqty + $sparkqty;
echo "Items ordered: ".$totalqty."<br />";

if ($totalqty == 0) {

echo "You did not order anything on the previous page!<br/>";

} else {
		if ($tireqty > 0) {
		echo $tireqty." tires<br />";

	}

	if ($oilqty > 0 ) {
	echo $oilqty."Bottles of oil<br />";
	}

	if ($sparkqty > 0 ) {
	echo $sparkqty."Spark Plugs<br />";
	}
}

$totalamount = 0.00;

define('TIREPRICE', 100);
define('OILPRICE', 10);
define('SPARKPRICE', 4);

$totalamount = $tireqty * TIREPRICE
	     + $oilqty * OILPRICE
	     + $sparkqty * SPARKPRICE;

$totalamount = number_format($totalamount,2, '.',' ' );

echo "<p>Total of order is $".$totalamount."</p>";
echo "<p>Address to ship to is ".$address."</p>";

$outputstring = $date."\t".$tireqty." tires \t".$oilqty." oil\t"
		.$sparkqty." Spark plugs\t\$".$totalamount
		."\t". $address. "\n";

// open file for appending

@ $fp = fopen("$DOCUMENT_ROOT/../orders/orders.txt", 'ab');

flock($fp, LOCK_EX);

if (!$fp) {
	echo"<p><strong>Your order could not be processed at this time. 
			please try again later.</strong></p></body></html>";
	exit;
}

fwrite($fp, $outputstring, strlen($outputstring));
flock($fp, LOCK_UN);
fclose($fp);

echo "<p>Order Written.</p>";
?>
</body>

my suspiscions are windows will not give it permision to make a file, or that the document path is not acurate

i would look forward to any advise you have i understand best way to manage data would be through a database but im still learning,

That implies that fopen() is returning false, which means that there was some error in opening the file.

i agree totally, file permision? i think it may be the directions to the local root, ive got the example from a book, would my local root settings b dif on my pc, surely its just asking for the file named orders in the same folder the php file is kept?

Immyphp

guess what i worked out the answer thought i would write it anyway for other new people who may get stuck

the issue is simple the book wanted me to make a file in a document with in a folder but that folder did not exist so the answer was to make location of the file creation different. like this

$fp = fopen("$DOCUMENT_ROOT/../orders.txt", 'ab');
