source code for SERIALIZE() ???

[sneakyimp]

does anyone know where I might find out the exact procedure that

serialize()

uses on objects and/or arrays? unserialize() would be nice too.

I'm hoping to duplicate these functions in Macromedia Flash MX to facilitate data transfer. I promise to share the results with anyone who helps. This could be very useful!

You can download the php source....

[sneakyimp]

excellent! where?

php.net

Quick fgrep through the source, it looks like it resides in the ext/standard/var.c file.

does anyone know what "smart_str_appendl()" does? i think it's a c function, but i'm not sure...i don't see it defined anywhere in the c code for PHP.

oh hang on....i'm sorry...i'm not used to C code. i found this:

#define smart_str_appendl(dest, src, len) smart_str_appendl_ex(dest, src, len, 0)

and this:

static inline void smart_str_appendl_ex(smart_str *dest, const char *src, size_t len, int what)
{
	size_t newlen;

smart_str_alloc(dest, len, what);
memcpy(dest->c + dest->len, src, len);
dest->len = newlen;
}

#define smart_str_alloc(d, n, what) {\
	if (!d->c) d->len = d->a = 0; \
	newlen = d->len + n; \
	if (newlen >= d->a) {\
		d->c = SMART_STR_REALLOC(d->c, newlen + SMART_STR_PREALLOC + 1, what); \
		d->a = newlen + SMART_STR_PREALLOC; \
	}\
}

I have no idea what this code is doing. anybody care to clue me in?
