PHP Text Hit Counter: fwrite(): supplied argument is not a valid stream resource

[bubu]

I'm newbie in PHP and I am coding a simple text counter. I'm using PHP version 4.3.4 in Xitami 2.5b4 and WinXP Pro.

When I execute the php file, this is the output:

./kounterfiles/~hitcounter~index.php.txt
Warning: fwrite(): supplied argument is not a valid stream resource in D:\WebDevelop\local\hitcounter\index.php on line 29

Warning: fclose(): supplied argument is not a valid stream resource in D:\WebDevelop\local\hitcounter\index.php on line 30

Hit Counter: Error opening file for reading.

Note: The "Error opening file for reading" is an error handler that I made due to the fact that it will overload ~350mb of RAM mem if it is not there. And also, it seems to be hiding the same error shown above it ("supplied argument is not a valid stream resource")...

Here is the code:

<?php

// Config settings here
$file_dir = "./kounterfiles/";
$file_ext = ".txt";
$currfile = $file_dir . str_replace('/','~',$_SERVER['SCRIPT_NAME']) . $file_ext;
echo $currfile;
// Log visit
function log_visit() {
	$fp = fopen($currfile, "a");
	//if (!$fp) {
		//echo "<br>Hit Counter: Error opening file for appending.<br>";
		//}
	//else {
		$today = getdate();
		$month = $today[month];
		$mday = $today[mday];
		$year = $today[year];
		$date = $mday . $month . $year;
		$line = $REMOTE_ADDR . "|" . $mday . $month . $year . "\13\10";
		fwrite($fp, $line);
		fclose($fp);
	//}
}

// Show visit count
function show_visit() {
	$fp = fopen ($currfile, "r");
	if (!$fp) {
		echo "<br>Hit Counter: Error opening file for reading.<br>";
		}
	else {
		$visits = 0;
		while (!feof ($fp)) {
			$line = fgets($fp, 4096);
			$visits++;
			//echo $buffer;
		}
		fclose ($fp);
	
		// Display visits count
		echo $visits;
	}
}

log_visit();
show_visit();
?>
