Hi,
I'm working on a script to look for a UUEncoded attachment in an NNTP
message. I'm running into problems with spaces in the filename of the
attachment.
UUEncoded files in the body of a message will start with the word "begin",
then the size of the file, then the name of the file. Then the encoded
file, finaly then a newline with only the word "end" like so:
begin 644 photo.jpg
-encoded image-
end
The script looks for that first line in that order so as not to confuse it
with the word "begin" showing up somewhere else in the message. Here is
the particular line of code that searches for that:
if (preg_match("/^begin\s+[0-9][0-9][0-9]\s+(.+?)\s*\r?\n/m", $body))
The part where you fetch the file name (.+?)\s* is what is causing the
problem as when the file name is "a something.jpg" then (.+?) matches a
then \s matches the space and the rest is skipped.
The problem I'm running into is with spaces in the file name. For example,
if it starts with this:
begin 644 a_nice_photo.jpg
it works just fine, decodes the image and places it below the text of the
message. But if the line looks like this:
begin 644 a nice photo.jpg
with spaces in the filename, the script seems to stop looking after the
"a", thinks this is just normal text in the message and doesn't decode the
image. This results in the raw UUEncoded text showing up where the image
should.
I'm stumped. Any ideas?
