preg_replace_callback, carrying variables

I've been struggling with this for a while.

Here's what I'm trying to do:

private function makeMiniTemplate($ARRAY){

/*

$ARRAY looks like this:
$ARRAY['h']='Some Value';
$ARRAY['mce']='Something else';

*/


$template=<<<allthis
<div>[h]</div>
<div>[mce]</div>
....

allthis;

/*
I want to replace [h] with $ARRAY['h'];
Drives me crazy not to be able to use nowdocs in classes but that's
another story...
*/


$template=preg_replace_callback(
"/\[(.*?)\]/s",
create_function('$matches','echo $ARRAY[$matches[1]];'),
$template);

return $template;
}


So, I don't know how to pass in $ARRAY as $ARRAY is not "scoped" inside
the create_function. It always comes up empty.

I don't see how to do this using callbacks either. I'm a little short of
understanding on how this works. I've tried a number of different
approaches.

How do I do this?

But to replace ALL [h] with $a:
$t = str_replace("[h]", $a, $t);

Quick 'n dirty:

<?php
$template = 'some [foo] stuff';
$values = array(
'foo' ='bar'
);

function replace($matches) {
global $values;
$name = $matches[1];
return isset($values[$name]) ? $values[$name] : '';
}

$result = preg_replace_callback('/\[(.+?)]/', 'replace', $template);
var_dump($result);
?>

gone "global". I'd also determined that it couldn't be done without a
callback (at least I couldn't!).
