scope problem

ko6

Hi all

Im having a scope problem. My script is using severalinclude() calls, nested one in another. At some point, all of the variables/constants defined in an upper file, are not recognized in the included file.

so if I do something like this in file1.php:

$test="test";
include ("file2.php");

and then in file2.php in the first line its written:
echo $test;

I get a notice/warning about "Undefined variable".

note that it is STILL recognized AFTER the include is finished in file1.php. For some reason its not passed further down the include.

I guess its either a bug or some sort of php setting that needs to be corrected, since the same file that is included in someplace else, but not so deeply, and works fine.

Ill be happy to get some help.

Could it be that the files are not properly included due to incorrect paths?

No. If that would have been the case, I would get an error about the file not found. The file is being proccessed for sure, or else these notices wouldn't have been issued in the first place.

I see.

Create 2 files in the same directory:

<?php
//test1.php
$test = "hello world";
include 'test2.php';
?>

and

<?php
//test2.php
echo $test;
?>

Run test1.php and see what results you get.

Basically, the idea here is to write the smallest and simplest script that demonstrates this problem.
If you cant re-produce the problem, then you would have fixed it.
If you can find it, then you can focus on the problem and fix it.

Ok, I already tried that. it worked. I did it with 6 nested includes, and it still worked. but in my script it doesn't, and I cant figure out why.

Within my script i tried to do something like you have written: right before the include I defined a variable, and in the first line of the included file I tried to print it. No good. still doesn't recognize it or anything else from outside of this specifig file.

The funny thing is, that AFTER the include is done, and i try to print this variable, its ok. So its not that it gets undefined, but its like for some reason an entire new and clean scope is opened for the included file...

You'll need to post the relevant code snippets from your actual code then.

ok, here goes:

file1.php:

<?
$test_thing="something";
include(SHOP_MANAGE_URL."header.inc.php");
echo $test_thing;

?>

header.inc.php

<?
echo $test_thing;

?>

now, when it reaches the echo line in header.inc.php (the one from the include, that for sure), it issues a wraning. after that, in the echo in file1.php, it print "something" without a problem.

The problem is that I cannot reproduce your error.
What isnt wrong cant be fixed.

You have to give code that I can run out of the box (or at least nearly there), and yet reproduces the error that you experience.
You should also state the exact error message, not merely your interpretation of it.

ko6

ok. np:
thats the error (not a php error, but bad enough for me):

Notice: Undefined variable: test_thing in {path in here}header.inc.php on line 2

I thougt I was clear about it. Like I said - it doesn't recognize it. I tried to reproduce the problem myself using up to 7 files that included each other, but I couldn't see anything wrong with it. The original script is more complicated than that, but the code I gave you was taken from it, and still $test_thing should have been printed as far as I can tell...

hmm... on a hunch, is SHOP_MANAGE_URL an absolute URI?

ko6

an absolute path. a correct one.
/usr/home/somthing/something.../header.inc.php

darn, then I'm out of ideas, short of working with your actual code.

Basically, I remembered that if an absolute URI (not local path, URI with HTTP) is used, then variables go out of scope since the file isnt included as usual.

ko6

well, tnx for tying anyway. youre not the first (not inclduing me) that has no idea what is happening here.

once again. tnx.

The reason why people cant effectively help you is that they simply dont have enough information.

Unfortunately what's hindering you is that you dont know what info to provide, as the problem is pretty opaque to your attempts to solve it.

Still, there is the fact that you can run tests designed to fail in the same way that dont.
Then use those to re-write your script.
