ULONGLONG in PHP?

Code: [Select]

0x1A
BNLS_VERSIONCHECKEX2

(DWORD) Product ID.*
(DWORD) Flags.**
(DWORD) Cookie.
(ULONGLONG) Timestamp for version check archive.
(STRING) Version check archive filename.
(STRING) Checksum formula

anyone know how i can mimic the ULONGLONG in php? I'm a bit stumped.

I don't think PHP supports 64-bit ints, if not, just treat it as a set of 2 32-bit ints.  Its jsut the filetime, not really used for anything.

You're correct; it does not.

A FILETIME is defined as ...

Code: [Select]

typedef struct _FILETIME {
  DWORD dwLowDateTime;
  DWORD dwHighDateTime;
} FILETIME,
 *PFILETIME;

... per MSDN.

That definition is written in that manner because, back in the day, there wasn't support in C compilers for __int64.  While it's technically accurate it really doesn't provide any meaningful value to someone who's trying to reverse-engineer the actual date, other than to say that you could possibly translate with some fancy bit math.

Well, thank god the reverse engineering here has already been done, eh? That definition can be recreated in PHP fairly easily, I think.

Huah reverse engineering?
Its a 64-bit unsigned int. If your language can not handle that large of a number, split it up, this number in particular is really of no use {unless you're going to download the file from bnftp} so does it really matter?

The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). PHP does not support unsigned integers. Integer size can be determined using the constant PHP_INT_SIZE, and maximum value using the constant PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5.

Fully documented language FTW
