I'm working on a application written in "C" that needs to parse and
understand php arrays that have been serialized and stored in a MySQL
table. I started writing the parser and realized its not a trivial
task. I'm wondering if there is any source code in C to do what I'm
looking for? I googled many different combinations of keywords and
nothing useful came up. I even looked at the code in
ext/standard/var_unserializer.c, and I don't think what will port to a
stand alone application without extensive modifications.
Why not? It is a rather simple re2c parser. Don't look at
var_unserializer.c, look at var_unserializer.re and read up on re2c.

You would obviously want to replace the creation of internal PHP data
types with whatever you want to unserialize to in your app, but I don't
see how you would find any code somewhere else where you wouldn't need
to yank out the destination code from since that is going to be the
unique part in each implementation. And if you use the same re2c
grammar that PHP uses, it will be correct. Using any other
implementation likely wouldn't be.
Of course, I also wouldn't suggest using serialized PHP for a target
that wasn't PHP. Why don't you look at json or perhaps wddx instead?
