Help!!! 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.[pre][pre][/pre][/pre]

You can't include php script files that are on remote servers, at least, you shouldn't. Think of the security flaw!

try this:

 

file1.php

 

 

<?php

 

$c=4;

 

include 'file2.php';

 

 

runFunction($c);

 

?>

 

 

file2.php

 

<?php

 

function runFunction($c){

$a = 2;

$b= 6;

 

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

 

return $sum;

}

 

?>

When you include a remote file you only get any HTML output produced by that file.

 

So, the question becomes, not what are you doing, buy why are you doing this? There is likely a more proper way of doing what you want, if you tell us what it is you are trying to accomplish.

It's a little hard to explain, but I'll try.

 

I need to have a script on server websites. Depending on some conditions that are inserted into the variables, I need the script to request a query on the database of another site and that other site answering with the result.

 

You see any way of doing this without including files? How would you do it?

Sites in same domain or different?

[bpops]

The best way would be to generate a GET post to the script you're running (the one you were going to put in include), then print the results.

Sites in same domain or different?

 

Different... otherwise I would do the query directly...

[PFMaBiSmAd]

Actually, the question should be is the same database server accessible by all the domains? Different domains under the same hosting will all likely have access to the database server.

Can you give a code example? (Yes, I'm that new). Thanks

This are external domains not hosted on the same server. So, no access to the database. That is why I need the query to be run from a file on the server with the database.

If the mysql server allows external/remote access you could do this directly by just putting in the proper host in the mysql_connect() function.

 

If not, there are several existing "remote mysql helper" scripts that include security. Here is a link to one such script - http://www.phpclasses.org/browse/package/4000.html

It allows but it won't be possible to use it in this case since it only allows after IP validation

 

I'll check the script you suggested. Thanks a lot. I'll probably be back asking more question on this.

 

Meanwhile, if anyone has any other suggestion, I'll be thankful.

Would it make more sense to have the information stored in several files on the main site and, depending on the needs, having the info fread and then fwrite on the requesting sites?
