Here it is, just wrote it up

<title>PHP Unique Hits Counter ( Using flat files )</title>
</head>

<body>
<?php
// File where we will store the counter data
$counterFile = 'counter.txt';

// The user's IP
$userIP = getenv( 'REMOTE_ADDR' );

// Read the file into an array ( every line of the file will be a piece of the array )
$contentArray = file( $counterFile );

foreach( $contentArray as $lineNum=>$lineContent )
{
	// Split each line by |
	list( $IP, $visits ) =  explode( '|', $lineContent );
	
	// Make sure the visits is recorded as an integer
	$uniques[ $IP ] = (int) $visits;	
}

if( $uniques[ $userIP ] > 0 )
{
	// If it's a returning visitor, increase the # of visits from their IP
	$uniques[ $userIP ]++;
}
else
{
	// If it is somebody's first visit, add them to the list and give them 1 visit
	$uniques[ $userIP ] = 1;
}

//=================
// Update our counter file
//=================
foreach ( $uniques as $ip=>$visits )
{
	$newContent .= "$ip|$visits \n";
}
if( $handle = fopen( $counterFile, w ) )
{
	if( !fwrite( $handle, $newContent ) )
	{
		echo 'Error updating counter file!';
	}
}
else
{
	echo 'Error opening counter file';
}

//=================
// Final # of unique visits.
// If there is only 1 unique visitor, we don't want the "s" at the end of visitors
//=================
$totalUniques = count( $uniques );
$visitorsEnd= ( $totalUniques == 1 ) ? false : 's';

echo 'You have visited this site ' . $uniques[ $userIP ] . ' times <br />';
echo "We have had $totalUniques unique visitor{$visitorsEnd}.";
?>
</body>
</html>

I threw in a little proper grammer. Just make sure that the counter.txt file is writable
