Regular Expression Result as Associative Array Index

Hi Everyone.

$layout=ereg_replace("\[\[([a-z:0-9]+)\]\]", $dillo['\\1'], $layout);

I'm trying to use the result of a Regular Expression Match as an Index
for the Associative Array $Dillo[], so that the to-replace content can
be controlled from the to-be-replaced content.
Unfortunately the code above doesn't seem to work.
Any ideas?

Sorry about my poor english, i'm workin' on that.

The ereg_* functions will not be available in the PHP 6 core so you'd
better get used preg_* equivalents:

If you need a match then you must use preg_match() rather than
preg_replace().

Try this code:

<?php

$Dillo = array(
'alvaro:99' => 'Hello, world',
);
$layout = 'foo:bar[[alvaro:99]]';

if( preg_match('/\[\[([a-z:0-9]+)\]\]/', $layout, $matches) ){
$layout = $Dillo[$matches[1]];
}

echo $layout;

?>

Of course, you'd need some extra checks.
