filesize() with Bad Filenames

rgraves

I'm trying to find the file size of various files and it seems to be crashing on files with bad filenames (specifically files with spaces in their names).

Is this a problem with filesize()? I haven't seen it documented anywhere. Does anyone know how to get the file size for files with special characters or spaces in them?

this is new to me. can you show a filename which you can't do a filesize and the code that does so?

I'm trying to get details on a file and then output it using header(). Here's the header code:

header('Content-Type: '. $mimes[$ext] .'; filename="'. $fullpath .'"');
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");	/* fixes IE problem with opening PDFs (see ctemple comment on http://ca3.php.net/readfile) */

header("Content-Length: ".@filesize($fullpath));
readfile($fullpath);
exit;

Now this is working for filenames like "test.txt", "file.jpg", "document.doc", etc. When I tried it on a file called "test test.txt", it doesn't work. I tried a bunch of things and one of them was to comment out the above code and echo the variables like this:

echo "fullpath = $fullpath<p>";
echo "size = ". filesize($fullpath);
print_r(stat($fullpath));  // I tried this when I saw filesize() was returning nothing

I noticed filesize() was returning nothing for the bad filename. stat() also returned nothing. But for normal filenames, both filesize() and stat() worked.

Any ideas?

If on a UNIX/Linux system, I think you need to escape the spaces. Maybe you could do something like:

$filename = str_replace(" ", "\\ ", $filename);

I think I figured it out.

Long story short, I'm using apache to redirect non-HTML files through a file handler (don't ask why). So when I went to "www.mydomain.com/test test.txt", the browser converted the filename to "test%20test.txt". Headers still worked using this, but doing a filesize() on that filename failed because the actual file in unix does not have a %20 in it.

It all makes logical sense now!

ah, that. when trying to get files from urls, you must use urlencode()
