PHP Variables & Include problems

JoelyUK

Hi,

I seem to be having some problems with includes and the passing of variables into those includes :-(

The code I'm trying to use thats not working is:

<?php

session_start();

global $page;

$page["PAGE_TITLE"] = "Welcome";
$page["CSS_LINK"]= "http://resources.domain.com/css/standard.css";
$page["LEFT_STRAP"] = "Welcome Guest";
$page["RIGHT_STRAP"] = "";
$page["MENU_LOCATION"] = "home";

@include("http://resources.domain.com/inc/html.php");
@include("http://resources.domain.com/inc/body-header.php");
?>

html.php then has PHP in to echo the page title, CSS link etc.

However, these won't show up unless I use these include paths:

@include("resources/inc/html.php");
@include("resources/inc/body-header.php");

I thought it might have something to do with global variables, but it seems PHP is intent on not passing the array $page over to pages included with [url]http://[/url] or another domain in.

Is there any way round this, or how to get the above code working?

Cheers.

Joel

This is what include does and does not:

http://www.php.net/manual/en/function.include.php

That's all there is to it.

Makes perfect sense if you think about it. include() will happily fetch a file from a http URL. Regardless of whether it's "local" or not, it's treated as a remote file.

PHP is a server-side process. What do you suppose is in that data stream by the time it gets to your PHP script? Certainly not PHP code, because any PHP in the original file has already been processed. All you will see is the results.

If you remote-include() a library file, you're including nothing but blank text.

GBahle

well said.

Something i just thought about (though i never tried it). You might (and that's a big "might") be able to work around the obvious problem if you create php code as a result of the original php file.

Meaning sth like this:

<?php
         print "<?php print \"Hello World\"; ?>";
?>

Most likely it'll just output the argument of the outer print as plain text.

Anyway, anyone test this, let me know the result 😉

Well I've figured it out now.

It means calling the file with the query string/variables on the end, or using local file paths (which I really don't want to do)

Possibly the stupidest question of the month, but:

Can you put a whole array into a GET?

i.e. index.php?page=$page

$page being an array

If not, is there some easy code to break it down into a query string?

Cheers.

In my case it works, as the "library" file contains some HTML too, with just a couple of PHP echo's for the CSS, page title etc.

And again..sorry....

Is it not possible to tell PHP the subdomains are local (although it's still being fetched by HTTP 🙁 ) , possibly via the include_path?

GBahle

you could use explode and list to build your query string, if you want to transmit the entire array.
Or you could use a session.

JoelyUK

Um, don't suppose you could give us an example with the explode method.

I haven't really used explode() much 🙁

GBahle

my mistake, it'd be implode() instead of explode. Anyway, this is probably simpler:

$qString = "?"; // start your query string 

foreach($page as $key => $value) {   // append all array values
	$qString .= "$key=$value&";
}

$qString = substr($qString, 0, strlen($qString)-1); // cut the closing "&"
