Including remote files

amarques

Hi,

This is probably a very basic question to many of you, but I'm just starting in PHP.

I need for a variable to be used on a remote file that is included and a new variable from this included file to be used on the script.

I'll try to demonstrate:

On my file1.php I have

<?php

$c=4;

include 'http://www.example.com/file2.php';


$multiply=$sum*2;

echo $multiply;

?>

On my file2.php:

<?php

$a = 2;
$b= 6;

$sum=$a+$b+$c;


?>

It is always returning 0 as in multiplication of 2 against and empty $sum variable.

What am I doing wrong? What is the best way to do such a thing? I'm sure there is a way to do it, probably altering the scope of the variables, but again, I'm just starting and would really need your advice.

Thanks for any help.

That will not work. If you include a file using a URL, all you get back is the client side output. Variables from the included file will not exist in your current file.

Thanks laserlight.

Do you see any other way of doing this?

Maybe it helps if I'm more precise on what I need:

I need to have a script on server websites (different servers, no db access to the main site). Depending on some conditions that are inserted into the variables, I need the script to request a query on the database of the main site and it answering with the result.

hmm... what considerations do you have on security?

:queasy: I was thinking to have the script on the main site connect to the database using a user that can only read from it. Further on than that, I haven't really thought about...

Okay. Admittedly I am not sure what is the best way to handle this, but I think that you should take a look at CURL.

I'll take a look at it. Thanks for your help
