sending a file with php

I'm trying to write a script that will send a file for download, or an image or text page for viewing by the browser, but when I view anything other than text with it it can't seem to get the client to see the file as what it really is, a picture file or whatever. Here's my current code (with comments)

The 3rd line is disabled for testing purposes, but when enabled, will surpress errors so they don't mess up the file. I have tested it with that line uncommented.

Code:

 <?PHP
 	//disable errors, those will screw over my file...
 	//ini_set('display_errors','off');
 	//get the location of the file and its name
 	if ($file = $_GET['f']) {
 		//is the file there? if so, open it.
 		if (!$fopen = fopen($file, 'rb')) { return_404(); }
 		//what is the file's mime type?
 		if (!$mime = mime_content_type($file)) { return_500(); }
 		//what is its size?
 		if (!$size = filesize($file)) { return_500(); }
 		//send mime and size in headers.
 		header('Content-Type: '.$mime);
 		header('Content-Length: '.$size);
 		//send file
 		if (!fpassthru($fopen)) { return_500(); }
 		//close fopen
 		if (!fclose($fopen)) { return_500(); }
 	} else {
 		return_404();
 	}
 	//404 error
 	function return_404() {
 		//send error headers.
 		header('HTTP/1.1 404 Not Found');
 		header('Status: 404 Not Found');
 		die;
 	}
 	//500 error
 	function return_500() {
 		//send error headers.
 		header('HTTP/1.1 500 Internal Server Error');
 		header('Status: 500 Internal Server Error');
 		die;
 	}
 ?>
 

any ideas?

 

All I can say is to double check the MIME headers, and see if it is sending the correct ones.

 

well, I forgot Content-Disposition: and Connection-Close:, and now it sends anything, but I can't get it to work with Content-Disposition: inline, it wants me to download the file... any ideas?

 

nevermind. it works right, just not how I expected it to.
