Reverse Engineering

[Anon]

I'm trying to do a little re-engineering of some PHP code, and the pages I'm working with make extensive use of includes. Is there some way I can maybe run php from the command line and pipe the code with all the includes to a text file so that I can see the code that the php compiler is actually compiling?

Thanks! Dan

Not really, because includes are executed at runtime.
So the number of includes depends on whatever the program is doing.

for example: this does not include anything if $a=0:

if ($a==0)
{
include("FiftyMegs_o_code.php");
};

In other cases a file may be included several times, making a grand-total completely unreadable.

You'd be better of just using 'grep' to search for all the include-statements. Unless the previous author went out of his/her way to make things difficult to read, you can say:

  grep "^ \tinclude" .php

and get a nice listing resembling this:

in_out.php include('io_util.php');
in_out.php include('io_post.php');
io_post.php include('io_main.php');
io_post.php include('io_main.php');
...
login.php include('io_util.php');
usrvw.php include('usrmsg.php');

Using awk, perl, or even php itself to clean this up and make
a real cross-referenced list is left as an exercise for the reader. :-)
