Ok I am going to put the entire class here for review... I am not the
original author, simply trying to get it to work because I think its pretty
neat: Here is the file, asciiartist.php:

Re: [PHP] tmpfile() errors?
You're not even trying to open a file. You're trying to open a Resource,
which makes me think that fopen() is being called twice or something. You
obviously have something very wrong.
Can you show the code around these lines where you're trying to open the
file? All of the errors are because of the first one.

RE: [PHP] tmpfile() errors?
I'd check the owner of the directory you are trying to write to. It needs to be
owned by the same user as the httpd process runs as.

Subject: [PHP] tmpfile() errors?
Here are the errors I am recieving:
Warning: fopen("Resource id #4","wb") - Permission denied in
/path/to/asciiartist.php on line 295
Warning: Supplied argument is not a valid File-Handle resource in
/path/to/asciiartist.php on line 296
Warning: Supplied argument is not a valid File-Handle resource in
/path/to/asciiartist.php on line 297
Warning: getimagesize: Unable to open 'Resource id #4' for reading. in
/path/to/asciiartist.php on line 303
ASCIIArtist(): Cannot determine image type of shared/image02.jpg.
I have checked the file permissions for the files and directory in question
and they are all set to read & write, so I know this is not the problem.
Here is the function that I am trying to get to work.
function ASCIIArtist($image)
{
if ($input = @fopen($image, "rb")) {
$image_data = fread ($input, 2048576);
fclose($input);
$tmp_image = tmpfile();
$output = fopen($tmp_image, "wb");
fwrite($output, $image_data);
fclose($output);
} else {
exit("Cannot access ".$image." for reading. (Does not exist or
has wrong permissions)");
}
This code is from http://www.sebastian-r.de/. And everything works fine
until it hits this function. Could I get some enlightenment on why it cannot
create a temp file named $tmp_image? (ecspecially when the permissions for
the file are correct?) Thanks in advance,
Jas
