[Resolved] Im so new and so confused

[gemione]

Here is my code:

<? 
	//**Catch variable values from Flash program**//
	$filename = $_POST['filename'];
	$day = $_POST['day'];
	//**Open/Create current user access log and copy contents to string**//
	$file = fopen($filename, "a+");
	$currentLogStr = fread($file, filesize($filename));
	fclose($file);
	//**Check to see if log has entries
	if ($currentLogStr != ""){
		//**If log has entries make array out of data**//
		$currentLog = explode(" ",$currentLogStr);
		//**Check to see if current day is later than last entry date**//
		if ($day > $currentLog[count($currentLog-1)]){	
			//**If current day later, add to log**//
			$file = fopen($filename, "a+");
			fwrite($file,$day . " ");
			fclose($file);	
		}
	}else{	
		//**If current day later, add to log**//
		$file = fopen($filename, "a+");
		fwrite($file,$day . " ");
		fclose($file);	
	}
	//**If current day not later than last entry do nothing**//
?> 

My problem is this. the $filename = "something.txt" and it will save in the same directory as the script fine. However i want it to save in a sub directory called logs. This is the code I tried:

$file = fopen("/logs/$filename", "a+");

It wont save. Please help, as well as suggest improvements. Ive been doing php for 2 days ever since i joined this forum.

Thanks😕

you will need to do something like this:

$file = fopen($_SERVER['DOCUMENT_ROOT'] . "/logs/$filename", "a+");

in *nix you are actually referencing the root directory of the server with that code. the path you want is probably something more like /home/user/public_html/logs
when working with the filesystem its different from the usual <img src="/image.jpg"> which looks for image in YOUR base directory, but fopen("/image.jpg") looks in the servers base directory.

OMG if I knew you i would buy you a beer!!! I was messing around with that soo much. Sometimes it would work, sometimes it wouldnt. Now it just plain works.

Thanks😃

yeah you can either use the document_root variable as shown above, or manually code it in yourself, but using the variable will work server to server and also saves you if you ever move or something.
