Remote PHP calls.

[wu78754]

I have a simple question which I do not know the answer.

I have two programs: A.php and B.php.

From within A.php I call B.php.
B.php will return a random number.
A.php will then write that random number into a file.

My trouble is in passing the random number back into A.php.

Help!

Here is some additional information.
A.php resides on

http://a.com/,

and
B.php resides on

http://b.com/.

imagine this

include 'B.php';
echo $myRandomNumber;

$myRandomNumber = md5(uniqid('',true));

your question is really one of variable scope. there is a very good manual section on this topic.

Thanks.
I am not sure you can include a remote php file. It would be a security issue if you can.

I just found the answer I was looking for.

$exurl ='

http://ticketeddy.com/test/B.php';

if (!($contents = file_get_contents($exurl))) {
echo 'Could not open remote URL.';
}
else {
echo $contents;
}

ah. i did not understand that they were on separate file systems, although I saw that they were on separate web urls.

use file_get_contents then

$myRandomNumber = trim(file_get_contents('[URL unfurl="true"]http://www.domain.com/path/to/B.php'));[/URL]

assuming B.php just echos a random number to screen

echo md5(uniqid(mt_rand(), true));
