Well, I think I'd approach this using preg_match_all() to break out all your
elements for replacement into an array, then look them up and produce a
second array of the desired replacements, and then do a preg_replace using
those two arrays to do your desired replaces.
Something like (completely untested!):
$matches = preg_match_all('|\[(.*\)]|U', $sentence, $items);
if ($matches):
$replacements = array();
foreach ($items[1] as $i=>$item):
$replacements[$i] = /* random item looked up in "$item.php" */;
$items[1][$i] = '|\['.$item.'\]|'; // reconstruct as valid preg
pattern
endforeach;
$new_sentence = preg_replace($items[1], $replacements, $sentence);
endif;
Cheers!
