Get variable from other PHP Page

DigiDan

Hi Guys,

Complete n00b question. What's the best way to get a variable from another page that's been called by

require_once("engine_client.php");

and then I'm calling a function that's in the "engine_client.php" file like so;

callEngine('engine.getJobs');

Any ideas?

Regards,

Dan

Dunno if it's a newb question. It's a question of scope. Can we see the variable declaration from "engine_client.php"?

Global variables from the calling script are accessible in the called script, though that's a bit messy (i.e. there's a link between the two .php files that you can't actually see/define very well). As such, there are usually better ways of doing it, e.g. wrapping the functionality in a custom function or class.

As requested, here's the variable declaration from engine_client.php;

function callEngine($method, $args = NULL)
{
    global $engine_xmlrpc_address;

// print("$method\n");

list($success, $response) = XMLRPC_request($engine_xmlrpc_address, '/RPC2', $method, $args);

if ($success)
{
    if (is_array($response))
    {
        printf("%s returned: ", $method);
        print_r($response);
    }
    else
    {
        printf("%s returned: %s\n", $method, $response);
    }
}
else
{
    echo($response['faultString']);
    exit;
}    

return $response;
}

And as for

...I'm sorry, what now?! I'm not a complete n00b but still learning the ropes!

From what I understand about what you were saying, a variable in my script doing the

require_once("engine_client.php");

can be read in the script being called, in this case engine_client.php?

That's great to know, but I need it the other way around, so that the variable set in engine_client.php (see above code for variable declaration) can be called in the script doing the

require_once("engine_client.php");

. Make sense?

Thanks for your help guys 🙂

IANAE ... if I'm reading things correctly though, you should get $response back from the function call, and the global variable $engine_xmlrpc_address should be available. But I might be wrong 😉
