Hi,
first of all, I'm not 100% sure this is a bug, but I think it is. anyway, here goes:
I manually connect to a php script, by simulating a browser's call. I want to sent some data by simulating a multipart/form-data POST. The data I sent is binary, but since I want to put this data directly into a database, I don't want to use the Content-Disposition: form-data; name="whatever"; filename="C:\whatever.exe" header.
This header would cause php to create a file in the tmp dir, and I don't want this. I simply want the binary data I send in a variable.
What I did was to set the following header: Content-Disposition: form-data; name="whatever"
(without the filename="C:\whatever.exe" part). After that I sent the binary data.
This should create a variable $whatever on the server.
Everything works just fine until my binary data contains a NULL [chr(0)]. What happens is that php creates the variable $whatever, but truncates everything after the NULL character (including the NULL character itself).
Of course you wouldn't be able to send a NULL from a normal multipart form input box or textarea on the web, but I think php should be able to create a variable which contains my NULL character and everything that follows when I manually connect. It correctly creates a file (including the NULL) when I sent the 'filename="whatever"' header.
By the way, if my form contains more parts after the binary part with the NULL character, php creates those variables correctly... but it just truncates everything after a NULL when I don't send something like filename="c:\whatever.exe".
here is a copy of the headers I manually sent:
*START*
POST /script.php HTTP/1.1
Content-Type: multipart/form-data; boundary=---------------------------7d12b732260086
Host: www.myserver.com
Content-Length: [The correct length]
-----------------------------7d12b732260086
Content-Disposition: form-data; name="whatever"
123[NULL]456
-----------------------------7d12b732260086
Content-Disposition: form-data; name="foo"
normal text, not binary
-----------------------------7d12b732260086--
*END*
my script on the server now has 2 variables; $whatever and $foo.
print $foo; #this prints "normal text, not binary"
print $whatever; #this prints "123", while it should have printed "123 456" (the space here simulating the unprintable NULL character).
I hope this all makes sense (I'm not sure it does 🙂 ).
Anyway, has any of you experienced similar problems, and maybe come up with a solution?
thanks in advance
Jeroen
